General The COM Sports Car Club is a not‐for‐profit organization with membership open to any person interested in sports cars and sports car events. The overall goals of COMSCC's Driver Schools and Time Trial Event are to: 1) Conduct a track event that puts everyone’s safety first. 2) Provide a driving instruction program that allows drivers to acquire and develop skillful driving techniques for enhanced driving pleasure and improved competitive ability. 3) Provide a time trial competition format that rewards both speed and consistency and includes a trophy class for every car that wishes to compete, provided it meets the safety requirements outlined in these rules. 4) Maximize track time. COM time trials are run in the spirit of good sportsmanship and are designed to provide competition for sports cars, racing cars and sedans. Entrants are not guaranteed competitiveness for any vehicle in any class. Cars may move between 3 types of classes and 15 total classes (including 8 Touring classes, 3 Street Prepared classes, and 4 Prepared classes) provided they meet all the specific rules (including safety rules) of the class into which they wish to move. COM has approved the following course configurations for Drivers Schools and Time Trials: • New Hampshire International Speedway: o North Chicane ‐ South Oval; Counter Clockwise Direction o North Chicane ‐ South Chicane; Counter Clockwise Direction o North Oval ‐ South Chicane; Counter Clockwise Direction • Summit Point (Main Track): Clockwise Direction • Summit Point (Shenandoah Circuit): Counter Clockwise Direction • Mt. Tremblant o Short Course, Clockwise Direction o Long Course, Clockwise Direction • Lime Rock: Clockwise Direction • Watkins Glen o Short Course, Clockwise Direction o Long Course, Clockwise Direction • Canadian Tire Motorsport Park –CTMP (formally Mosport International) o Clockwise Direction • Calabogie Motorsports o Long Course, Clockwise Direction • Monticello o Long Course, Clockwise Direction • New Jersey Motorsports Park ‐ Thunderbolt o Long Course, Clockwise Direction 3

Entry Procedure 1) To enter a COM event, entrants must be a current member of COMSCC in good standing, and hold a valid drivers’ license issued by the state or province in which they reside. Each entrant must fill out the appropriate registration form in full and present it to the event Registrar along with the appropriate fees. On the morning of the event, all entrants must present their State or Province issued drivers license for inspection by the Registrar. 2) Cancellation refunds are only given if the entrant has notified the registrar 7 days prior to the first day of the event. Entrants who are registered for both days of a two day event and who experience a mechanical breakdown on the first day which prevents them from participating on the second day, may obtain a refund for the second day provided they notify the Registrar prior to the end of the first day. 3) A driver may enter two or more cars in one or more classes but must pay an entry fee for each. 4) A late entrant is one who shows up after trackside registration closes at 8:15am. The registration, tech inspection, and actual running of a late entrant will be at the discretion of the event chairman (or chief instructor during drivers' school). If allowed to run, a $25 late penalty fee will be charged to the entrant.

Driver Requirements
General 1) Drivers must be at least 18 years of age. Due to constantly changing insurance regulations and state laws, drivers under 21 years of age may be required to produce a signed and notarized release form. Please contact registration well in advance of event for further information and appropriate forms if necessary. 2) Driving a car on a race track requires your full attention, and can be both stressful and tiring. COM’s primary goal is to run a safe event for all participants. Prospective drivers, if they have a disability or medical condition that could affect their ability to take instruction and operate their car, must disclose their condition at time of registration. While COM is committed to allowing all who wish to share our love of high performance driving attend our event, we reserve the right to decline a registration if we aren’t convinced your condition can be accommodated, to ensure your safety and that of the other participants. 3) A Driver Competition Log (DCL) will be issued to each driver at his/her first event upon producing a valid State Driver's license. 4) A driver will be classified as a student until his/her Driver Competition Log is signed by the Chief Instructor for a COM Time Trial license. Before being allowed to compete in a Time Trial, a driver must have a COMSCC Competition License or be classified as “Safe to Solo” by his/her individual Instructor. “Safe to Solo” will apply to the one full practice and time trial day following the school day only‐ that is, the second day of the event. For the next event, the driver will sign up as a student again, until the COM Time Trial license is earned. 5) Drivers and passengers must wear a Snell Foundation M or SA approved safety helmet at all times while on the course. At least M2005 or SA2005 approval is required. Note –COMSCC’s policy is to update this rule every 5 years to ensure helmets are no more than 10 years old. For example, after the 2014 season, the approval dates will be moved to M2010 and SA2010, respectively. COM reserves the right to reject for use any helmet that appears damaged or otherwise unsafe. 6) In an open car, occupants must wear the following while on course: a. Goggles or face shield; if vehicle is equipped with a stock windshield, eyeglasses, or sunglasses will be accepted. b. Arm Restraints c. For the purposes of this rule, an “open car” is defined as a convertible, Targa, T‐Top, or other vehicle that has no solid roof structure as delivered from the factory (e.g. formula car, sports racer, etc.) An open car with a soft top raised is still considered an open car. d. An open car with a hardtop in place is considered a closed car for the purposes of this rule only 7) Occupants must wear, at a minimum, long sleeves (NOT NYLON), long pants and suitable footwear. Cleated shoes, heavy boots and sandals are not permitted. Fire resistant suits and gloves and suitable footwear are recommended in all cars. NYLON CLOTHING IS NOT ALLOWED. 8) Occupants of vehicles that are classified in a Prepared Class, have acquired 51 or more Touring Class Modification Assessment points, or have acquired 16 or more Touring Class Engine Modification Assessment Points are required to wear a minimum of a single layer fire resistant full length suit and gloves and suitable footwear. 6
9) At no time during the Time Trial or on‐track session will passengers be allowed on the course unless one occupant is a COM instructor or a person designated by the Chief Instructor. All occupants must be COMSCC members, and registered for the event.
Passing 1) Passing is allowed only in those areas defined at the Driver’s Meeting. 2) Drivers being overtaken by other cars are expected to: a. Remain on the racing line b. Signal to the overtaking driver on which side he/she would prefer the pass to be performed 3) If the passing driver does not receive a point‐by signal within a reasonable length of time, he/she may inform corner workers with a “pit‐in/catch” signal (closed fist extended outside the driver’s window). Corner workers shall call Control upon acknowledgment of the signal and Control will then make a Black Flag decision, possibly directing the unyielding driver into the pits for consultation. 4) A point‐by signal is only an acknowledgment of the presence of the passing car and an indication of the preferred side for the pass to take place. It is in no way a command for the passing driver to execute the pass. The passing driver may not pass without having received a point‐by. If the driver chooses to pass, they shall pass on the side directed. 5) It is always the responsibility of the passing driver to execute a safe pass within the defined passing zone. Should a driver execute a pass without having received a point‐by and cause what is deemed by the Event Chair as an unsafe situation, proper disciplinary actions will be taken.
Licensing 1) COMSCC Licenses are issued for an initial period of three (3) years. Following the initial three (3) year period, licensed members must participate in at least one (1) COMSCC event per year to maintain an active license. At the discretion of the Chief Instructor, members whose licenses have lapsed may be required to attend a COMSCC event as a Student in order to reactivate their license. 2) The Chief Instructor may temporarily suspend or permanently revoke the COMSCC license of any member whose driving or on‐track behavior is considered a significant safety risk. License suspensions and removals may be appealed in writing to the Board of Directors.
Pit & Paddock Conduct 1) Consumption or influence of alcoholic beverages and/or intoxicating drugs before the completion of the last run of the day (or end of driver's school) will cause immediate disqualification and possible ejection from the event with no refund. This rule includes drivers, crew, officials, guests, and workers. 2) Unsafe, reckless, or unsportsmanlike driving or behavior anywhere on the course, in the pits, on the access roads, or any other area within COM's jurisdiction is grounds for immediate disqualification and possible ejection from the event with no refund.

3) All pets must be leashed at all times. Please check with the track before you make the trip, to ensure they permit pets at all on the grounds. 4) Shirts, long pants and shoes are required in pit lane and on track. Some tracks require helmets (e.g. bicycle helmets) in the hot pits; this will be covered in the driver’s meeting if it is a track requirement 5) No one under 16 is allowed in the pits or on the track while the track is open. 6) A driver is responsible for the actions of his pit crew and guests, including 1, 2, 3, 4, and 5 above. 7) No cars are allowed to loiter or reverse in pit lane, unless permitted by the Chief of Control.

Car Requirements Any vehicle or driver failing to comply with any item in Sections VI and VII below will not be allowed to run until the failed items are corrected. 1) Tires and Wheels a. Higher than normal inflation pressures are recommended for competition. Consult an Instructor if you have any questions. b. No cuts, bruises, ply separations, or body rubbing on the sidewalls is allowed. c. All wheels must be free from bends or cracks. d. Wire wheels will be rejected if they have more than two adjacent loose spokes or more than three total loose spokes on a wheel. e. Hub caps and trim rings must be removed. f. All lug nuts or wheel bolts)must be in place and tight. It is recommended that nuts be torqued to specification. In addition, every stud must be long enough to thread into the lug nut a length at least equal to the stud diameter. For example, a 1/2" thread diameter must thread into the lug nut at least 1/2". Closed end lug nuts are allowed, but it’s the competitor’s responsibility, for his own safety, to confirm this minimum engagement is met. 2) Brakes a. Wheel bearings must have minimal play. b. Brake fluid reservoir must be full. c. Brakes must be capable of stopping the car quickly and in a straight line. d. All vehicles are strongly recommended to run braided brake lines, as COM drivers have experienced failures with new OEM flex lines while on track. In particular, Ford Mustang Cobra 1994‐1998 must not use “as delivered” front flex lines. e. Use of aftermarket cross‐drilled rotors is discouraged. 3) Suspension a. Suspension must be suitable for high speed cornering and handling. Loose, soft, or worn shock absorbers, soft springs, sloppy ball joints, etc., are grounds for rejection of the car. b. Drag racing suspension modifications such as car raising, "Up Loc" or similar weight transfer devices, etc., are entirely unsuitable for controlled cornering and shall cause rejection. c. Steering gear and linkage must have minimal play. 4) Engine Compartment a. Engine compartment must be clean with no oil, water, or gas leaks. Hoses, lines, wiring and belts must be in good condition and securely mounted. The battery must be securely mounted. Exhaust system must be firmly mounted. b. The use of nitrous oxide is prohibited in all classes. Cars having nitrous systems installed shall indicate such on the pre registration form and tech sheet. The nitrous supply (bottle) shall be unhooked and removed from the car. Removal shall be verified at tech inspection. 5) Automobile Exterior a. Cars must be generally neat, clean, and suitable for the event. 9
b. All exposed headlights and glass lenses must be completely covered with tape. Plastic lenses need not be taped. Clear tape is allowed. All cars must have operative and exposed brake lights, except Formula Prepared class cars. Formula Prepared class cars must have rain lights. c. Removable hardtops may be removed and convertible tops may be lowered. T tops on 914s, X1/9s, Corvettes, etc., will be allowed if they are structurally sound. Tonneau covers or any soft removable cavity cover must be removed. d. All cars, except Prepared Class cars, must be equipped with a full height and width windshield. Side windows on the front driver’s and passenger doors will be all the way open unless noted at the drivers meeting. Rear windows may remain closed. Window nets are highly recommended. e. Car numbers and class must be placed on both sides of the car before Tech Inspection. All markings must be easily readable by corner workers. Numbers must have a minimum height of six (6) inches. Class designations must have a minimum height of 3 inches. Numbers and class designation shall be on a vertical side panels or vertical side windows and shall be of contrasting color to the car. Novice drivers will place three vertical stripes on each rear quarter panel and trunk lid. Magnetic numbers are permissible provided they are secured to the vehicle, which is the responsibility of the driver of the vehicle. 6) Vehicle Interior a. All loose gear must be removed before coming to Tech Inspection. If the spare tire is carried in the car, it must be firmly secured. Passenger seat back must be tied down or secured in position. b. All cars must have well mounted, metal‐to‐metal, quick release lap and safety belt and upper body restraint in good condition. Mounting points must be sturdy and immovable locations on the chassis, unibody, or roll cage/roll bar/harness bar. Suitable backing plates should be used where necessary. Refer to manufacturers, FIA and/or SFI mounting specifications for more information regarding hardware, backing plate, and installation requirements and suggestions. Touring Class cars may use any DOT, SFI, or FIA approved harness. Prepared Class cars, any car that has acquired 51 or more Touring Class Modification Assessment points, any car that has acquired 16 or more Touring Class Engine Modification Assessment Points, or any car that has removed front airbag(s) must use an SFI or FIA approved harness with a minimum of 5 points (2 lap belts, 2 shoulder belts, and at least 1 anti‐ submarine belt). i. All harness belts must have the SFI or FIA date certification label and be current (i.e. not expired or out of code). Generally, SFI belts are certified for 2 years and FIA belts are certified for 5 years. Certification date begins as of the date of manufacture, not the date of installation into the vehicle. ii. When constructing bars for harness attachment, be aware of the potential safety hazard that can be created by the addition of a horizontal bar directly behind the driver’s seat. In the event of a rearward impact the driver’s seat can be broken allowing the occupant(s) to impact the horizontal bar resulting in serious or fatal neck injuries. Suggestions for avoiding this potential hazard include moving the horizontal bar as far to the rear of the car as possible, utilizing a mount that is direct to an existing portion of the car or installing a full roll bar with an upper seat support. c. If the passenger seat is to be occupied, its seat belt restraint system shall have equal or greater restraint capability to the drivers’ seat belt restraint system, including type, width, and number of points. This is to ensure that the passenger is not subjected to aggressive driving that the driver would be willing 10

subject himself to, based on the level of driver seat belt restraint. For the same reason, any driver using arm or head and neck restraints must also provide the same for the passenger. Novices and other students not yet licensed by COM must train in a vehicle possessing a minimum of two seats and safety equipment for both seats appropriate to the class, of which one seat is to be occupied by an approved instructor. Roll bars are required in all Prepared Class cars, cars that have acquired 51 or more Touring Class Modification Assessment Points, cars that have acquired 16 or more Touring Class Engine Modification Assessment Points, and in all convertible and open cars regardless of class. Roll bars are permitted and strongly recommended in all classes and may be required in the future. A roll bar is a steel one‐ or two‐ hoop roll‐over protection device, solidly mounted to the structure of the car, and provides two inches of space between the top of the roll bar and the top of the driver’s helmet. Commercially available “harness bars” and “style bars” are not acceptable roll‐over protection. i. Factory installed roll‐over protection on open cars is not acceptable. Specifically, the Porsche Boxster or Boxster S/993/996 convertible system, the Honda S2000, and Mazda MX‐5 Miata factory equipment are not acceptable for competitive use. Convertibles may not use removable hardtops as a substitute for roll bars. A competitor may appeal to the Chief of Tech for acceptance of factory‐installed OEM roll‐over protection. The decision by the Chief of Tech is final. ii. Guideline minimum roll bar specifications are: iii. Cars up to 1500 lbs use 1.375 x 0.095 DOM/seamless/alloy iv. Cars 1501‐2200 lbs. use 1.500 x 0.095 DOM/seamless/alloy OR 1.500 x 0.120 ERW v. Cars 2201‐3000 lbs. use 1.500 x 0.120 DOM/seamless/alloy OR 1.750 x 0.095 DOM/seamless/alloy OR 1.750 x 0.120 ERW vi. Cars 3001‐4000 lbs. use 1.750 x 0.120 DOM/seamless/alloy (no ERW allowed) vii. For guidelines of material selection and construction practices, consult the Sports Car Club Of America (SCCA) General Competition Rules. Cars with roll cages that are constructed to SCCA GCR or other recognized sanctioning bodies’ specifications are not bound by the material selection criteria mentioned above. viii. All roll cages/bars must be padded with non‐resilient material such as Ethafoam or Ensolite with a minimum thickness of ½” in all areas which may come in contact with the driver’s and/or instructor’s helmet. Similar padding is recommended in areas where the driver’s and/or instructor’s arms or legs may come in contact with the roll cage/bar. In Touring classes where a passenger seat and dashboard are required, these items may be modified or removed to the extent required to accommodate roll bars, roll cages, or other safety equipment.. Note – the addition of a roll bar or roll cage and/or removal of interior and other components may affect the Competition Weight. See Classification section for details. Helmets must be a minimum of 2 inches below the top of Targa Top vehicles. Window nets are permitted in all classes. In addition, for all Prepared Class cars, cars that have acquired 51 or more Touring Class Modification Assessment points, or cars that have acquired 16 or more Touring Class Engine Modification Assessment Points either window nets or arm restraints are required. The following safety equipment is allowed in ANY class: i. Fire extinguishers and fire systems ii. Master electrical kill switches 11
iii. Fuel cells iv. Windshield/window clips and restraints v. Towing Hooks vi. Flywheel scatter shields 7) Miscellaneous a. Automobiles involved in an incident causing damage must be inspected by a COM Scrutineer or the Chief of Tech before being allowed back on the track. b. All in car, or exterior mounted video equipment must be securely mounted , and must be in place when the car is brought to tech inspection for review and approval by Tech. 8) Track imposed maximum sound limits are generally in effect at COM events for all classes. Sound limits are set by the tracks, and may change for each event. Each competitor is responsible for meeting track‐specific sound limits. For Time Trials, a noise violation results in disqualification with no points awarded for the event and no refund.All cars shall be powered by gasoline, diesel fuel, biodiesel fuel or electricity (provided by batteries) alone or in combination. Gasoline may be leaded or unleaded. Gasoline may include race gas limited by the SCCA fuel GCR to prevent toxic chemical use. Pump gasoline including Methyl or Ethyl Alcohol (Methanol or Ethanol) as limited by SCCA GCR may be used. Methyl or Ethyl Alcohol as a primary fuel is prohibited. Small amounts of Methyl or Ethyl Alcohol may be injected into the engine for engine cooling and detonation control when mixed with at least 50% water. No more than 1 gallon of such mix shall be carried in the car to ensure that it is not a primary fuel. Whenever an alcohol/water mix is injected into the engine it shall be considered a fuel and the tank must follow the same rules as other fuels

Flags 1) Command Flags ( Note, not all flags are used at all tracks; the specific flags in use will be reviewed at the driver’s meeting) a. GREEN Course is clear. b. STATIONARY YELLOW No passing! There is a problem on the course ahead of you. Proceed with caution. During timed runs, you are still being timed. c. WAVING YELLOW No passing! There is a problem immediately ahead of you. Slow down. Drive carefully; prepare to take evasive action. During timed runs, the clock will stop and you will be allowed a re‐run. d. RED Stop now! Stop in a controlled manner, in sight of the next flag station. Watch your mirrors while stopping to avoid being hit from behind. If possible, get clear of the course to allow passage of emergency vehicles. Stay stopped and in your car, with helmet and safety belts in place, until given a standing yellow flag and then proceed slowly back into the pits. e. BLACK Pull into the pits immediately for conference with authorized personnel who will make themselves known to you. There is something wrong with you or your driving. This flag may be used to end a practice session. f. BLACK FLAG WITH ORANGE CENTER (Meatball) Pull into the pits; there are mechanical problems with your car that must be corrected before you can continue. You must receive clearance from the Tech Inspector or Starter before returning to the course. During timed runs this is a did not finish (DNF). g. CHECKERED You have completed your timed run or practice session. Continue your lap at reduced tempo and with no passing, and pull into the pits the next time around. This is a cool down for you and your car. 2) Informational Flags a. DIAGONAL RED AND YELLOW STRIPES (oil or debris) Slippery track conditions. Caution. b. WHITE Caution: Emergency, official vehicle, or competitor vehicle at slow speed on the course. The vehicles being protected by the white flag may be passed provided the pass is done in a safe manner. c. BLUE (blue with diagonal yellow stripe) Another vehicle is catching you and/or following closely. Be aware! Do not change your line. If the vehicle is faster than you, it is recommended that you indicate which side you prefer to be passed on by motioning with your hand in that direction at the next available passing zone.

Time Trial Points & Guidelines 1) COMSCC championship series time trials consist of several events during the course of the year. This series will be based on a cumulative points system where points are earned by participating and placing in events as follows: a. 2 points for participating in the events plus: 1st place 9 points 2nd 7 3rd 5 4th 3 5th 2 b. To receive participation points, the competitor’s vehicle must cross the designated Start‐Finish line at least once, provided that the time trials are completed. If the event is held, but time trials are canceled or can’t be completed, every competitor shall receive participation points. To receive finishing points, the competitor’s vehicle must complete a minimum of one timed lap. c. If more than 6 points‐scoring events occur in the series, the lowest scoring event for each competitor will be dropped from the points totals for that competitor. A missed event yields zero points, and therefore becomes the dropped event. d. At the end of the year, additional points (including fractions) equal to the average number of cars per event will be added to the points of each class winner to determine the Overall Driver Championship. The Board of Directors may, from time to time, assign additional points to given events, to encourage participation in those events. These points will be assigned before the first event of the season. e. Ties in the final point totals shall be resolved on the basis of each participant’s record of First Place finishes: then if necessary, Second Place finishes: then if necessary, Third Place finishes, and so on until a winner emerges. If this procedure fails to produce a result, they shall be considered tied for the position in the standings. 2) An entrant must be a member of COMSCC to participate in a Driver’s School or Time Trial. In order to be eligible for year‐end Class Championship (1st, 2nd, 3rd, or 4th), a driver must have entered at least (3) events during the current year in the same class. in addition, for any Class Champion to be eligible for the Overall Driver Championship, that class must have an overall average of 2.0 or more participants per event for the season. 3) There may be no more than two drivers for a particular car in a particular class participating for trophies. Additional drivers may run, but not for trophies or for points in class. The contending drivers must be made known at Registration. 4) Trophies will be awarded at COM events as follows: 1, 2, or 3 car class 1 trophy 4 or 5 car class 2 6 to 9 car class 3 10 to 14 car class 4 15 to 19 car class 5 6 20 or more car class 14
5) Year‐end trophies will be awarded on car class average as follows: Less than 4.0 1 trophy Greater than or equal to 4.0 to less than 6.0 2 Greater than or equal to 6.0 to less than 12.0 3 Greater than or equal to 12.0 4 6) The driver completing all 3 time trial laps whose lap times are within a smallest range will receive the Consistency Award for the event. 7) In a single event, drivers may count only one car in each class for points. Points earned in each class may count towards the Class Championship for that class. Points from only one class finish during that event may be counted towards the Overall Driver Championship. 8) If the event is canceled (i.e. we never get on the track) due to circumstances beyond the control of COM Sports Car Club (e.g., weather and/or track conditions), no points will be awarded. Should an event be delayed or canceled, COM is not required to provide a refund nor should a participant expect to receive a refund. However COM will make every effort to provide a partial refund for any funds in excess of the overhead costs incurred by COM Sports Car Club. 9) A Time Trial run is considered completed if all cars scheduled to run have completed their timed runs. All competitors submitting time cards to Timing & Scoring are scheduled to run unless Gridding is notified by the competitor of a DNS status. Should an event be closed for any reason, the determination of which cars are scheduled to run will be based on the information Gridding has at the time of the conditions causing the event to close. 10) If an event is closed for any reason before all Time Trial runs are completed, then the event will be considered canceled. All participants will receive participation points as if the Time Trial had been completed. Classes in which all cars scheduled to run completed at least one of their timed runs prior to the event being closed will receive their respective class points in addition to their participation points, but these points will not count toward the Overall Driver Championship. 11) Only times taken by Timing and Scoring during Timed Runs will be considered for a class record. Competitors who believe that they have set a new class record must present their car to Scrutineering for inspection, to verify compliance with class requirements. Information necessary to show original configuration (shop manual) and documentation of the modifications done and points taken (Touring Class classification Sheet) is the competitor’s responsibility. If the car is found to not comply with the rules for that class, the record will not be awarded, and the car will be disqualified. The Points Keeper will record the lap records. 12) Any car exceeding the maximum decibel limit of the track where the time trial is taking place shall be disqualified. No points shall be awarded to the driver(s) of disqualified vehicles. The driver may appeal this decision to the BOD prior to trophy presentation ceremony if the noise violation was that cars first offense/warning of the event. 13) An entrant may appeal a decision made by a Chief of Specialty in writing to the Board of Directors. This appeal must be made within 7 days following the date of the decision being appealed. The Board of Directors will vote on the appeal at the next Board Meeting and deliver their decision to the entrant. Affected parties who are Board members or Officers of the club are not permitted to vote on the appeal. 14) A particular Car/Driver combination is only allowed one time trial attempt (excluding catches). If a Car/Driver doesn’t arrive for staging, or the Car/Driver leave the track for any reason (such as a pit entry for mechanical),
15
15) 16) 17) 18)
they will be scored according to the time trial rules. The Chief of Timing and Scoring may add cars/driver to new or existing run groups or change run group order at its discretion. If a competitor causes a catch due to driver error, they will be disqualified. An example, but not limited to, would be a car that spins off track, then enters the track again, causing the car behind them to catch them. If a competitor causes cars to become out of order, they will be disqualified. An example, but not limited to, would be a car that spins off track, and then enters the track again, after other cars have passed. If a mechanical failure or driver error (as determined by Chief of Control or Chief of Timing and Scoring) causes the time trial to be stopped, that driver will be disqualified, and the remaining drivers will get a re‐run. Disqualification of a competitor for any reason must occur before the trophy presentation ceremony at the end of the time trial day, or by the end of the time trial day in the event that no presentation ceremony is held.

Classification System Definitions Factory Trim – refers to unmodified vehicle components (or components of an identical fit, function, and purpose) included on the car year, make, model, and body style listed for purposes of the Showroom Assessment as delivered by the manufacturer within the respective domestic market; Example‐ a 1965 Mustang is bought with a standard 289 2 bbl carbureted engine. The owner then replaces the 2 bbl carburetor, cast iron intake, and 2 bbl heads with Ford OEM 4bbl carburetor, aluminum intake manifold, and High Performance heads as used on the Hipo Mustang and Shelby. These parts were available “over the counter” at the Ford dealer, not just as part of a new car, so a claim that they are “factory” could be made. However, as these parts were not on this car as it left the factory, points for Non‐Factory carb, intake, and heads must be taken Modification Assessment – total number of assessment points pertaining to non‐Factory Trim modifications to a vehicle; see Modifications Assessments section of the rules for points assessed for each modification – for modifications not explicitly listed in the Modifications Assessments section of the rules, points for each modification will be provided by Scrutineering Showroom Assessment – point value assigned to each car for the purpose of classification within Touring Classes; see Appendix A and B for list of Showroom Assessments – for vehicles not explicitly listed in Appendix A and B, Showroom Assessment will be provided by Scrutineering Showroom Base Weight (SBW)– factory listed curb weight for a production vehicle; used in determining the appropriate number of Modification Assessment points for cars competing in a Touring Class Total Assessment – the sum of the Showroom Assessment and Modification Assessment, used to determine Classification within Touring Classes Touring Class – a type of COMSCC Time Trial classification where vehicles are classified based on the sum of a Showroom Assessment based on the vehicle’s potential and a Modification Assessment for any modifications performed to the vehicle Vehicle Competition Weight – the total weight of vehicle plus fluids, driver, ballast and any and all safety and other equipment during competition

Overview COMSCC Time Trial includes 15 distinct classes for competition, 8 Touring classes, 3 Street Prepared, and 4 Prepared classes. Vehicles are classified into a Touring class based on the Total Assessment, comprised of a benchmark Showroom Assessment plus any additional Modification Assessments acquired through performance modifications added to the vehicle. Vehicles are classified into Street Prepared or Prepared class if a vehicle’s Total Assessment exceeds the Maximum Class Assessment of the 8 Touring classes. Classification within Street Prepared and Prepared classes is generally unlimited and based on cylinder count; details are outlined in subsequent sections.
Classification Procedures 1) Prior to competing in a Time Trial, each entrant must submit to Scrutineering a classification sheet prior to the close of Tech. Inspection on the day of the Time Trial – Scrutineering will collect and make competition sheets openly available to all entrants 2) Entrants are solely responsible for proper classification of their own vehicles. New competitors may receive classification assistance at Tech Inspection from Scrutineering, but are highly encouraged to contact the Chief Scrutineer via email with questions well before the event to minimize delay on the day of the event. Whereas vehicle class is most important from a competitive perspective on the second (time trail) day, Scrutineering is available during the first day of the event to help answer specific questions as they arise. However, no event official is responsible whatsoever for the proper classification of the vehicle. 3) Entrants are also responsible for policing of competing vehicles within their class. To ensure that competitors are classifying their cars within the rules of the club and to promote proper vehicle maintenance, a secondary inspection by a Tech Inspector or Scrutineer may be done to a random sampling of cars in any class. Scrutineering reserves the right to re classify a vehicle at any time. False information supplied by an entrant about their car or themselves is grounds for disqualification. Inspection may include, but is not limited to: a. Inspection of vehicle components and modifications b. Weighing of vehicles c. Request for additional documentation to substantiate horsepower, torque, or weight claims, if scales are not available; Scrutineering will consider any and all documentation available, including scale printouts, dyno sheets, spec sheet for “sealed” or “crate” motor, list of engine modifications, etc. If documentation is not available upon request, the competitor may be disqualified. The competitor may then request an appeal and provide the necessary documentation. 4) All protests must be presented verbally or in writing by the entrant to a Scrutineer. No classification protests affecting a given event will be accepted after the end of the last time trial run of that event. 5) Protests may only be filed by event competitors of the same class, Scrutineers, and Event Chairpersons. Event competitors can protest the classification of a car participating in another class that he or she believes is incorrectly classified and should be competing in their class. 6) If a competitor is protested and it is found that the competitor’s car is not legal in the previously declared class, the competitor will be disqualified. 7) A competitor may appeal a Scrutineering decision in writing to the Board of Scrutineers. This appeal must be made within 7 days following the time of the protest in question. The complete Board of Scrutineers will vote 18
on the appeal and deliver their decision to the competitor before the next time trial event. This decision may not be appealed to the Board of Directors. 8) Any discrepancy in the classification of a car between the vehicle tech sheet, timing card and class displayed on the vehicle will result in disqualification. It is the responsibility of each entrant to verify the accuracy of this information and correct any discrepancies with Registration and Timing and Scoring prior to submitting a time card. Participation points will be awarded to disqualified cars in the proper class. 9) Any track record must be validated by having a Classification Sheet inspected by Scrutineering after a competitor’s time trial run but before the conclusion of the event. Upon review of the competitor’s Classification Sheet, the Scrutineer may determine that additional inspection of the vehicle is required – see #3 above for details. If the car is found is not legal in the previously declared class, the competitor will be disqualified.

Touring Classes To compete in a Touring class, a vehicle must be a production vehicle with closed fenders, and in Factory Trim, approved by the US DOT or equivalent organization. In addition, all Touring Class vehicles must retain: 1) Interior a. Dashboard – must be of similar size, shape, and function as Factory Trim b. Passenger seat – must be an automotive seat, safely mounted, and suitable for an adult passenger; passenger seat may be removed when a “Petty Bar” is installed 2) Exterior a. All body panels must be present, including front and rear bumpers, hood, fenders, doors, windshield, roof (unless convertible), and trunk, and must not be modified in a manner that compromises safety capabilities in comparison to Factory Trim exterior panels; for example, if factory doors are replaced with fiberglass or carbon fiber of the same appearance, door bars for driver and passenger protection must be added to replace the factory door reinforcements. Vehicles not equipped with these body panels may run in a Touring Class, pending a safety inspection by a Scrutineer b. A, B, C, and other pillars may not be modified c. Brake lights must be operative and exposed d. Windshield wipers must be present e. Note – see Exterior section for modification points for certain exterior modifications NOTE: COM has developed a spreadsheet that simplifies the process of assigning your car to its proper Touring class, and we highly encourage its use. The most current edition of the spreadsheet is available for download from the club website. The following pages describe in detail the specific reasoning for the classification process. The process for determining the classification of a vehicle is threefold: 1) All vehicles must be assigned a Showroom Assessment, either through the Showroom Assessment Inventory (Appendix A) or provided by the COMSCC Chief Scrutineer prior to event registration. Generally, the Showroom Assessment Inventory uses the following methodology for assigning Showroom Assessment points to vehicles: a. Determine the weight‐to‐power ratio of the vehicle using factory listed curb weight, factory listed crank horsepower, and factory listed crank torque i. Formula: Curb Weight / (2/3 x HP + 1/3 x Torque) b. Convert the weight‐to‐power ratio to an meaningful points value for classification within Touring Class, this is achieved by multiplying the ratio by ‐4.25 and adding 114; these factors were chosen to: i. Create a proper distribution of vehicles across the 8 Touring Classes based on weight‐to‐power ratio, and ii. Ensure that the highest performing production vehicles are classed towards the top of the Touring Class structure c. Add an “adjustment” to the converted weight‐to‐power ratio to account for other factors that affect vehicle performance, such as suspension, weight distribution, drivetrain layout, aerodynamics, etc. Generally these assessments range from ‐10 points (e.g. Subaru Forester Wagon) for cars that have a significantly lower performance potential relative to their weight‐to‐power ratio up to +15 points 20
(Nissan GT‐R) for cars that have a significantly greater performance potential relative to their weight‐to‐ power ratio – See Appendix A, “Adjustment” column, for the adjustment on each car d. The sum of b (converted weight‐to‐power ratio) and c (additional performance “adjustment”) represents the total Showroom Assessment 2) In addition, a Modification Assessment must be determined by summing the total points acquired for the following: a. Any modification to the vehicle that differs from Factory Trim b. Vehicle Competition Weight, if below Showroom Base Weight, and c. Tire width, if different from the Touring Class Standard Tire Width for the Touring classification of the vehicle’s Showroom Assessment 3) A Total Assessment is calculated based on the sum of the Showroom Assessment and Modification Assessment, and then classification is determined based on the table below. Vehicles with fewer than 110 Total Assessment points will be classified into a Touring Class according to the table below. Vehicles acquiring 110 or more Total Assessment points will be classified in a Street Prepared or Prepared Class. Total Assessment 0 – 39.9 40‐49.9 50‐59.9 60‐69.9 70‐79.9 80‐89.9 90‐99.9 100‐109.9 110 and Above
Touring Class T30 T40 T50 T60 T70 T80 T90 T100 N/A – see Street Prepared/Prepared
For example: a vehicle with a Showroom Assessment of 57.6 and Modification Assessment of 8 would result in a Total Assessment of 65.6 and classification in T60. Note – a competitor may choose to compete any Touring class either at or above their determined Touring class (i.e. run “up” a class); in addition, any Touring class competitor may opt to run in the appropriate Street Prepared or Prepared Class (see separate section below for classification guidelines) Showroom Assessment – see Appendix A For kit cars or race cars not listed in Appendix A, a competitor may request a Scrutineer‐provided Touring Class classification. In these instances, the competitor must provide the peak horsepower, peak torque, curb weight, and other relevant technical specifications for the vehicle, as requested by the Scrutineer. There is no guarantee that 21
Scrutineer‐provided Touring Class classifications will result in placement in a Touring Class – i.e. the Scrutineer may decide to assess more than 109 Touring Class points, resulting in a Street Prepared or Prepared Class classification for the vehicle in question.
22
Modification Assessments Engine The Modification Assessment for engine modifications can be determined in 2 ways, either: 1) Competitor adds points for any and all assessments listed below – to be added to the Showroom Assessment and Modification Assessment points from other categories (e.g. suspension, brakes, etc.) to determine the total assessment. Or, 2) In lieu of adding points from the assessments listed below, prior to the close of event registration the competitor can opt to provide to the Scrutineer with a peak horsepower and torque figures, indicating wheel or flywheel horsepower. The Scrutineer will then use the following process to assign a total number of engine Modification Assessment points to the competitor using the following process: a. If necessary, estimate crank power by converting all wheel power figures (horsepower and torque) to crank power figures, assuming 18% drivetrain loss for 2WD cars, 20% drivetrain loss for 4WD cars. The formula to convert wheel power to crank power is Wheel Power / 0.82 = Crank Power for 2WD, Wheel Power / 0.80 =Crank Power for 4WD. If using Dyno Dynamics Shootout Mode figures, no conversion to crank power is necessary. b. Apply the same showroom assessment base class formula (described above) and appropriate Adjustment (same as original adjustment used for competitor’s vehicle during base classing) used to determine the showroom assessment while substituting the new power figures to determine a new assessment c. Determine the difference between the new assessment and original showroom assessment Note ‐ The competitor will not need to add any additional points for engine modifications from the list below. The competitor, upon receipt of the new engine Modification Assessment figure, may still opt for option 1 at their discretion In the case of option 2, the Scrutineer‐provided Assessment for engine modifications is final and may not be appealed. In either case, any and all Modification Assessment points for other areas (e.g. suspension, weight reduction, tires, etc.) must be added to calculate total Modification Assessment points. In some cases, specifically involving engine modifications not listed below and engine swaps, the Scrutineer may require a Scrutineer‐provided Assessment. In these cases, the competitor must provide peak horsepower figure(s), and use of this Assessment is not optional, i.e. the competitor may not use an Assessment based on engine modifications as listed below. Example: a competitor has a 1995 BMW M3 with 6 points worth of Engine Modification assessment points. They choose to request a Scrutineer‐provided engine Modification Assessment, providing to the Scrutineer their peak wheel horsepower and torque figures of 245hp and 240ft‐lb, respectively, along with any supporting documentation, if requested. The Scrutineer then provides an assessment of 9 points based on the peak power figures. The competitor has a choice – accept the 6 points from the table below, or accept the 9 points provided by the Scrutineer. Either way, the 23
competitor must still add the figure chosen, along with Modification Assessment points for other categories (e.g. suspension, tires) to the Showroom Assessment to determine the Total Assessment for classification. Example: a competitor has a 1991 Mazda Miata and has chosen to swap a stock 1996 Mazda Miata 1.8L motor. This modification requires a Scrutineer‐provided engine Modification assessment, and the competitor cannot choose to use the points from the table below. In this case, the Scrutineer determines the base class of the 1991 Miata to be 30.3. Substituting the new power figures (128hp, 114ft‐lb torque), the new assessment is 39.1. The scrutineer finds the difference between the 2 figures, and provides an assessment of 8.8 points for engine modifications. Again, the competitor must add the 8.8 points engine Modification Assessment figure to the Showroom Assessment, along with Modification Assessment points from other categories (e.g. suspension, tires) to determine the Total Assessment for classification. Note – the competitor must still use the 1991 Mazda Miata base tire width and base weight, which is listed as 170lb lighter compared to the 1996 Mazda Miata donor vehicle. This weight difference is worth approximately up to 4 points in terms of Weight Reduction Modification Assessment. Example: a competitor has a 2002 Subaru Impreza WRX with 19 points worth of Engine Modification assessment points. They choose to request a Scrutineer‐provided engine Modification Assessment, providing to the Scrutineer their peak wheel horsepower and torque figures of 265hp and 275ft‐lb, respectively, along with any supporting documentation, if requested. The Scrutineer then provides an assessment of 16 points based on the peak horsepower figure. The competitor has a choice – accept the 19 points from the table below, or accept the 16 points provided by the Scrutineer. Either way, the competitor must still add the figure chosen, along with Modification Assessment points for other categories (e.g. suspension, tires) to the Showroom Assessment to determine the Total Assessment for classification.

29
Weight Reduction Weight reduction modification assessment is based on the how difference between the Vehicle Competition Weight and the Showroom Base Weight. The Vehicle Competition Weight is the total weight of vehicle plus fluids, driver, ballast and any and all safety and other equipment during competition. Competitor must determine Weight Reduction Modification Assessment using the table below. This figure must be added to the Showroom Assessment along with any Modification Assessment points from other categories (e.g. engine, suspension) to determine the Total Assessment and Classification. Assessment Weight difference (Vehicle Competition Weight – Showroom Base Weight) ‐5 >200lbs heavier ‐4 161‐200lb heavier ‐3 121‐160lbs heavier ‐2 81‐120lbs heavier ‐1 41‐80lbs heavier 0 0‐40lbs heavier 1 1‐30lbs lighter 2 31‐60lbs lighter 3 61‐90lbs lighter 4 91‐120lbs lighter 5 121‐150lbs lighter 6 151‐180lbs lighter 7 181‐210lbs lighter 8 211‐240lbs lighter 9 241‐270lbs lighter 10 271‐300lbs lighter 11 301‐330lbs lighter 12 331‐360lbs lighter 13 361‐390lbs lighter 14 391‐420lbs lighter 15 421‐450lbs lighter 16 451‐480lbs lighter 17 481‐510lbs lighter 18 511‐540lbs lighter 19 541‐570lbs lighter 20 571‐600lbs lighter 1 Additional Point Each 30lbs lighter Note – weight reduction can be achieved by removing or replacing any non‐essential parts, unless otherwise mentioned, including: interior headliner, rear seats, carpets, insulation, air conditioner, radio, sunroof/moonroof, spare tire, jack, interior panels, console, etc. In addition, ballast is allowed up to 150lbs provided it is secured – location and security of ballast must be verified by Scrutineer.
30
Tire Compound Tire Compound Modification Assessment is based on the type of tire run during competition. Competitor must determine Tire Compound Modification Assessment using the table below. This figure must be added to the Showroom Assessment along with any Modification Assessment points from other categories (e.g. engine, suspension) to determine the Total Assessment and Classification. Any tires not classified below, either explicitly or within the designated DOT UTQG ranges outlined, must be disclosed and evaluated by the Scrutineer. Assessment Description 13 Non‐DOT Slicks (except where noted) Hoosier A6 Hoosier Radial Wets, H2O Continental Challenge Wet Tires 8 BFGoodrich R1‐S Hankook c90, c91 Goodyear RS AC Hoosier R6, SM6 BFGoodrich R1 Hankook c50, c51, c70, c71 6 Kumho v710 Toyo Proxes RR Continental Challenge Tires (not incl. Wets) DOT UTQG rating 41‐120, including Toyo RA1, R888 3 Nitto NT01 Yokahama A048 Kumho v700 Victoracer 1 DOT UTQG rating 121‐200, e.g. Hankook RS3
31
Tire Width Tire Width Modification Assessment is based on the width of the widest tire run during competition. Competitor must determine Tire Width Modification Assessment using the table below to determine the Showroom Assessment Class Baseline Tire Width. From there, points will be assessed based on how much wider or skinnier the competitor’s widest tire is from this Baseline Tire Width. Note – tire diameter and profile are free. Stock or factory Trim tire width for a particular vehicle is irrelevant. Showroom Assessment Class T100 T90 T80 T70 T60 T50 T40 T30 Baseline tire width +/‐ 10mm 315mm 305mm 285mm 265mm 245mm 225mm 205mm 185mm Assessment for tire width is based on the widest tire equipped on the vehicle. For example, if a vehicle is equipped with 225mm wide tires in the front and 255mm tires in the rear, the 255mm tire width will be assessed. Add 2 assessment points for tire width of 20mm wider than Showroom Assessment Class baseline tire width from table above (ex: for a vehicle in T60, add 3 points for 275mm wide tires). Add 3 points for 30mm wider, 4 points for 40mm, 5 points for 50mm, etc. Subtract 2 assessment points for tire width of 20mm skinnier than Showroom Assessment Class baseline tire width from table above (ex. For a vehicle in T80, subtract 4 points for 245mm wide tires). Subtract 3 points for 30mm skinnier, 4 points for 40mm, 5 points for 50mm, etc. Add 1 assessment point for the following oversized tires: all Hoosier DOT‐R and BFGoodrich DOT‐R tires Note – any wheel width and/or diameter is free, including offset, provided that the rim width used is among the rim widths recommend by the tire manufacturer for that particular tire size. Spacers up to ½” in width may be used, provided all lug/stud thread requirements are satisfied (see Car Requirements section for details). Rolling and/or flaring of fenders is also permitted. Non‐Factory Trim spacers, lug nuts, and studs are free.
32
Street Prepared Classes The intent of this classification is to provide a competitive grouping for vehicles which might be modified to improve performance, and safety, Street Prepared must address a wide range of modifications in order to find a class for any car between "Street Touring" and “Prepared” cars. Therefore it is impossible to guarantee the competitive potential of any car, even when modified to the full extent allowed by Street Prepared (SP). Kit cars and replicars are allowed in SP if they meet the rules otherwise specified. A Kit Car is typically a low production volume or one‐off tube frame car with fiberglass, carbon fiber or aluminum body. This car may either duplicate a classic sports car of the past (either faithfully or with performance improvements), or be a new design. A Kit Car must be street legal. A Kit Car is considered street legal if it otherwise meets the requirements of this rule book and has a current registration and inspection sticker or meets the New Hampshire Statutes on Equipment of Vehicles (http://gencourt.state.nh.us/rsa/html/NHTOC/NHTOC‐XXI‐266.htm) including the Street Rod statutes. Where applicable, it shall be the responsibility of the competitor to prove the stock configuration by providing a factory shop manual of the competing vehicle's model and year. “Stock configuration” is defined as having been available from the factory for that model and year, or having identical form, fit, and function to stock. This definition applies whether or not a performance gain is derived from a particular modification. A Kit Car competitor must be prepared to defend the street legality of his car by presenting state statutes from New Hampshire if the car is not registered or statutes from the state in which the car is registered. Cars which have been modified in violation of these rules will likely be classed Prepared class. However, these cars may qualify for entry into a Touring Class – see Touring Class section for requirements. Street Prepared automobiles must comply all requirements in the Car Requirements section, then any modifications are permitted while observing the following restrictions. 1) Interior a. Cars must be equipped with street interior consisting of stock dash board, door panels, side panels. Rear seat, all carpet, and headliner may be removed. b. Roll bars and roll cages are highly recommended c. The passenger seat may be removed when a “Petty Bar” is installed. The passenger seat must be an automotive seat, safely mounted, and suitable for an adult passenger. A harness of similar type to the driver's must be installed. 2) Exterior a. Cars must be equipped with wipers and wiper motor, head and tail lights, turn signals (front and rear), and horn. b. Stock glass windshield and rear glass must be used. c. Silhouette of car must remain as delivered, with the exception of aerodynamic changes as defined in item 10 below. d. Composite panels may replace hood, fenders, bumpers, doors, and trunk lid as long as stock appearance is maintained. Cars using aftermarket composite hoods must utilize hood pins. Cars using aftermarket 33
composite doors must have a roll bar or cage, and must have tubing of the same size and thickness as the roll bar/roll cage starting at shoulder height (while seated) and running forward and downward to at least 85% of the door opening. e.
