PURPOSE

  1. The Detroit Council of Sports Car Clubs (DCSCC) has established these regulations to govern the 2000 DCSCC Autocross Championship Series and to serve as a set of recommended practices for non-championship events put on by Council-member clubs.

  1. GENERAL

  1. The Rule Book shall be available for sale to all interested parties who are not registered for the Championship Series. (Registrants receive one free copy) Each DCSCC Club shall receive two free copies for Club use. There will be a fee of $2.00 per extra Rule Book to cover the costs of printing.
  2. The Council shall recommend dates for Championship Series events. All Championship events shall be held on Sunday or Detroit-area holidays. Council shall reserve the right to deny such recommendations to clubs which have not previously demonstrated their ability to sponsor Championship-quality events. There shall be no more than two (2) Championship events in any three-week period without specific approval by Council.
  3. Clubs sponsoring a Championship event shall submit to the DCSCC treasurer a sanction fee of $1.00 per entrant no later than thirty (30) days after the event, to establish a fund to provide suitable awards for Championship Series winners.
  4. In order to earn points in a Championship event, each driver must be a member of a Council club and must register with the Council as a Championship Series participant. Championship Series annual registration fee shall be $5.00 per participant.
    1. At registration, the driver shall receive an assigned number for the season, and a 2000 Rule Book (no charge).
    2. The driver shall score points from the date of his/her registration.
    3. Class Champions shall be awarded numbers in the order of their prior year points (best 2/3 of events). Higher numbers will be assigned by the Standings Official on a first-come, first-served basis.

  5. Changes in Championship Series event dates scheduling must be approved by the Council at least thirty (30) days prior to the running of the event, at a Council meeting
  6. Details of all Championship Series events MUST be on the Autosports Hotline, (248) 545-6733, by the Friday before the event at the latest.
  7. Registration fees for second drivers should be approximately one-half (1/2) the fee charged the first driver.

  1. ENTRY AND SAFETY REQUIREMENTS

  1. Every entrant's vehicle must pass the entry and safety requirements of the sponsoring club. In particular:
  2. Sponsoring clubs shall perform a technical inspection of each car entered, to cover such safety items as brakes, steering, and suspension. See APPENDIX IV SAFETY for a technical inspection guideline.
  3. All swing-axle cars, specifically including, but not limited to: Fiat 850, Triumph Spitfire MK I, II, III, pre-1965 Corvair, and swing-axle Volkswagen, must have adequate rear negative camber or acceptable camber limiting devices.
  4. All vehicles must have four (4) wheels, ten (10) inches or larger in diameter, and a wheelbase minimum of (72) inches, and a maximum of (117) inches.
  5. "Uni-Lug" type wheels are prohibited on all vehicles.
  6. All vehicles must have four (4) wheel brakes operable from a single control and must be self-starting.
  7. Non-production based cars must comply with the safety and construction standards shown in APPENDIX II STANDARDS FOR NON-PRODUCTION BASED VEHICLES.
  8. Seat belts and helmets are required to be worn by all persons riding in any car during all runs.
  9. A roll bar is strongly recommended in all cars, especially open cars and those on race tires.
  10. Non-stock seat belts must meet the standards in APPENDIX III NON-STOCK SEAT BELTS.
  11. Most clubs require driver's license, proof of insurance, and/or vehicle registration to register. If in doubt, check with the sponsoring club. Different clubs have different minimum age requirements; check with the sponsoring club.
  12. Registration shall not close before 1:00 p.m. at all Championship events. Registrant, attendant paperwork, and vehicle must be present at or prior to registration closing.
  13. Entry fees shall be refunded to persons refused entry, but not to those disqualified or ejected.
  14. The sponsoring club retains the privilege of denying entry, disqualifying or ejecting any entrant deemed unsafe or undesirable.
  15. Anyone under the influence of alcohol or narcotics may not compete in or be present at the event. There shall be no use of alcoholic beverages or narcotics during the entire length of the event by entrants, workers, or spectators.
  16. No driver may enter any event more than once and may not change vehicle classes after their first run.
  17. In the event that the sponsoring club needs to enforce a noise standard, the following is strongly recommended by the Council:
    1. Notice of noise enforcement and details should be on flyers and Hotline message, as a supplemental regulation.
    2. The noise standard should be a measurable, objective standard. If a sound measuring device is not available, a committee formed of the Event Chairs and sponsoring club Council Representative shall be able to determine noise compliance subjectively.
    3. Prior to first car out, a sound meter should be located at tech inspection for competitors to ensure compliance.
    4. It is the option of the sponsoring club as to the location of the sound meter during competition. It is recommended that the location and standard meet local ordinances (see below), and a log of potentially objectionable cars be kept for reference. Drivers of potentially objectionable vehicles will be notified.
    5. If a competitor violates the standard, a DNF should be assessed. A second violation will result in disqualification from the event. In this case, (1) point will be granted to the competitor for the Championship Series. Entry fee refunds are at the discretion of the sponsoring club.

NOTE: Federal, State, and Local noise standards require sound levels of less than 80 dBA at 50 feet when measured at wide open throttle and under straight line operating conditions with no wheelspin.

  1. CLASSIFICATION OF CARS
  2. The classification of a car is the responsibility of the entrant. The technical inspector(s) at each event shall use this Rule Book to assist the entrant to classify his/her car. The sponsoring club of an event may reclassify a car and adjust points if it detects an error after official results have been published, up to one week after results publication.

    The technical inspector(s) at an event should be able to help, but since internal modifications cannot be readily determined it is the entrant’s responsibility to correctly classify a vehicle

    1. DEFINITIONS:

  1. AUTOMOBILE (CAR): A self-propelled land vehicle, running on at least four (4) wheels, not in a line, which must be in contact with the ground when the vehicle is at rest. At least two (2) wheels must effect the steering and at least two (2) wheels must effect the propulsion.
  2. SEDAN: A car capable of transporting four (4) or more average size adults in a normal seated position.
  3. MODEL: A group of cars of a given make which have virtually identical bodies and chassis, but are readily distinguished from other models of the same make by virtue of major differences in body appearance and/or chassis design. The names by which the manufacturer designates these groups have no bearing on this.
  4. STANDARD PART: An item of standard or optional equipment that could have been ordered with the car, installed on the factory production line, and delivered through a dealer in the United States. Dealer-installed options, except as required by factory directives, no matter how common, are not included in this definition. This definition does not allow updating and backdating of parts.
  5. TRACK: The distance between the centerlines of the wheels as measured without driver, measured as follows: Take the distance from the inside of one wheel at the hub centerline height to the outside of the opposite wheel, then conversely from the outside of the first wheel to the inside of the other. The two dimensions obtained are to be added together and divided by two to obtain the average. These measurements are to be taken at the front and rear of the rims to compensate for toe-in/toe-out.
  6. RIM WIDTH: The measurement from inner bead seat to opposing seat.
  7. RACE TIRE: A tire manufactured expressly for race purposes and/or has "race tire" and/or "not for street use" imprinted on it. Cars equipped with race tires shall run only in their appropriate Prepared or Modified Class.
  8. RACING RUBBER RECAP: A street tire carcass recapped with racing rubber compound. This tire is classified as a race tire.
  9. ENGINE SWAP: An engine installed in a production car that is from an engine family that was not available as original equipment in any car of the same basic body style. Installing an engine from another vehicle of the same engine family and basic body style is not an engine swap, but does move the car to the class that engine normally runs in.
  10. GRAY MARKET CARS: Vehicles which were not imported for sale in the U.S. by an authorized distributor or the manufacturer. These cars may be classified in "Street Prepared" upon request to Council for classification.
  11. REPLICA KIT CARS: A car which has the appearance of a production automobile, in street legal trim, i.e. Cobra, Speedster kits. These vehicles shall be classified in "Street Prepared".

    1. CLASSES:
    2. All cars will be classified within group TSS to THS (Street Tire Stock), SS to HS (Stock), ASP to FSP (Street Prepared), TM1 to TM3 (Street Tire Street Modified), SM1 to SM3 (Street Modified), AP to FP (Prepared), or AM to FM (Modified). Cars not classified in TS, S, SP, TM, SM, or P will run in M subject to retroactive classification if submitted to Council for proper classification. Specific cars and classes are listed in XIII CLASS LISTINGS beginning on page 33.

    3. STREET TIRE REQUIREMENTS
    4. Tires not allowed in street tire classes include any tire with a tread wear rating below 140. If in doubt, have your Council representative check before you buy.

    5. STREET TIRE STOCK (TSS-THS) CLASS REQUIREMENTS:

  1. Any vehicle may run the street tire stock classes if it meets the class requirements for stock and is equipped with tires that meet the street tire requirements.
  2. Cars competing in Street Stock may not modify, exchange or add anti-roll (sway) bars, mounting links, or bushings (front and rear).

    1. STOCK (SS-HS) CLASS REQUIREMENTS:

    1. All cars must meet the listed stock class requirements to be classed in the basic stock class. Any modifications not specifically allowed will move the car into Street Prepared, Street Modified, Prepared, or Modified Class. If the car does not meet Stock Class requirements, its appropriate class shall be determined by preparation levels as listed in Article IV, Sections F through L.
    2. Cars running in Stock Class must have been series produced with normal road touring equipment capable of being licensed for normal road use in the United States and normally sold and delivered through the manufacturer's retail sales outlets in the United States. Cars not specifically listed in a Stock Class must have been produced in quantities of at least 1,000 in a 12-month period to be eligible in a Stock Class. Except for modifications authorized below, Stock Class cars must be run as delivered from the factory with only standard equipment as defined by these rules. Any other modifications or equipment will place the car in Street-Prepared, Prepared, or Modified category as appropriate. The entrant has the burden of proving that his car conforms to these rules by his owner's manual, manufacturer's catalogs, or other official manufacturer's documentation.
    3. Alternate components which are normally expendable and considered replacement parts (e.g. engine and wheel bearings, seals, gaskets, etc.) may be used provided they are the same type and size as the standard parts and used in the same location. Hardware items (nuts, bolts, etc.) may be replaced by similar parts of unrestricted origin.
    4. Authorized Modifications. If a modification is not specifically authorized in this or previous sections of these rules, it is NOT allowed.

    1. Bodywork:

    1. Accessories, gauges, indicators, lights, cosmetic aerodynamic devices and other comfort and convenience modifications which have no effect on performance and/or handling and do not materially reduce the weight of the car are permitted. This does not allow racing-type driver's seat substitution.
    2. Hood straps or fasteners may be added.
    3. Any fuel tank cap may be used.
    4. Windshield may be folded (but not removed) provided the required mechanism is standard equipment.

    3. No portion of the tire tread extends beyond the fender opening when viewed from the top perpendicular to the ground.
    4. When viewed at tech inspection, each tire must have measurable tread at two (2) points on the tire, which are 180 degrees apart around its circumference and which are within one (1) inch of the tread centerline. Tires may not be regrooved or show cord. (Tires with tread of less than 2/32" or wear bars showing are not in compliance with Federal, State, or Local laws for vehicles driven on the street.)

    1. Any type of wheel (of standard width and diameter) may be used provided it does not have an offset of more than + 0.25 inch from a standard wheel for the car. Wheel spacers are not allowed unless factory installed.
    2. The make of shock absorber may be substituted, providing that the number, type, system of attachment, and attachment points are not altered. Substitute shock absorbers may not alter ride height.
    3. The make and material of brake linings may be changed.
    4. Front anti-roll (sway) bars:

    1. The addition of any front anti-roll bar is permitted on any car not originally equipped. Anti-roll bars that are not original equipment must attach to the chassis in front of the front axle centerline. The attaching linkage for the roll bar to the suspension may be adjustable; however, when installed, must be all the same length. The anti-roll bar must be allowed to rotate in the chassis mounting brackets. No modifications to the bodywork, frame, or other components of the car are authorized, except for the drilling of holes for the mounting bolts.
    2. The substitution of front anti-roll bars is allowed on cars already equipped as long as the number of bars does not change. A substitute bar must use the original mounting points.
    3. The use of any bushing material is permitted.

    1. Standard, as defined herein, suspension springs must be used. They may not be cut, shortened, or collapsed. However, cars with swing-axles may be lowered sufficiently with spring modification to achieve no more than two (2) degrees negative camber.

  2. Brakes are required on all four wheels. Brake lines are to be steel with Aeroquip-type or automotive-type flexible hose connections. All lines must be securely mounted to the vehicle.
  3. Brackets must be securely mounted using bolt and nut attachments or equivalent. No wiring or taping of the brackets is allowed.
  4. Fire extinguisher must be carried on board, securely mounted, and readily accessible for release.
  5. A firewall must be constructed so as to provide a bulkhead of reasonable flame resistance between the engine and driver's compartment.
  6. The body/frame design must include bodywork at least up to the driver’s waist. Roll bar height must extend at least two (2) inches above the top of the driver's helmet with the driver normally seated in the car. Mounting points for the suspension must be suitably gussetted or braced. The driver's seat must be supported by solid structure. A floor pan must be installed under the entire area occupied by the driver.
  7. Fuel lines must be securely mounted and away from direct contact with any hot or moving components. All fuel connections must be tight and leak-free.
  8. The fuel tank must be a suitable container (portable gas containers are not acceptable) and must be securely mounted.
  9. An ignition kill switch must be installed with easy reach of the driver and must be labeled as such.
  10. A safety belt is required and must be in good condition. Belts must meet the requirements in APPENDIX III NON-STOCK SEAT BELTS.
  11. Steering must be considered safe by Tech Inspection. Steering wheel play must be negligible. All rod ends, etc. must be tight with a minimum 3/8 inch shank. Heim joints must be installed with flat washers to prevent pullout.
  12. Suspension components must be in good condition with regard to wear. All mounting bolts must be Grade 5 or better.
  13. Controls must operate in normal automotive fashion. Throttles must be actuated by foot and must incorporate a positive-acting throttle return spring attached directly on the throttle lever on the throttle plate shaft.
  14. Welds must appear and be strong. No burn through allowed.

    1. APPENDIX III NON-STOCK SEAT BELTS

Production seat belts in recent model cars are a very effective means of reducing injury in an impact. For the purpose of these rules, such belts are considered the minimum acceptable restraining system. Because of the rollover hazard, a shoulder belt should not be worn in an open car unless there is a roll bar or other adequate overhead structure; such a structure is assumed to exist in vehicles which were factory assembled with shoulder belts, and those belts must be worn in such vehicles.

Entrants are strongly encouraged to install an even better system for competition events (especially such events as Waterford Time Trials). There are a number of "competition belts" which are excellent if they are properly mounted; however, they may be less safe if improperly mounted, which could lead to serious injury.

Therefore, the following standards will be applied to all non-stock belts:

  1. If any shoulder belts are used which attach to the lap belt near the center of the lap, they must be used in conjunction with an anti-submarine (crotch) belt. The prevents the shoulder belt from pulling the lap belt upward during an impact, which could cause serious internal injuries.
  2. Lap belt must be located so that the belt leaves the lap at a downward angle of between 30 and 60 degrees from the horizontal.
  3. Shoulder belt mounts must be located so that the belt leaves the top of the shoulder at an angle of not more than 25 degrees below the horizontal (horizontal or higher is preferred). A low mount will generate compressive forces in the spine during impact, which could cause injuries. Where shoulder belts are mounted to a roll bar, the mount should be designed to minimize the likelihood of cutting the belt during a rollover.
  4. All belts must be located on either a factory stock mounting location or to a secure mount in the frame, body or roll bar/cage structure. Mounts to sheet metal must be suitably reinforced to prevent pullout. Any mount which is in any way removable, must be so attached as to preclude any possibility of coming loose during driving or impact. Remember, during a crash, the belts may have to absorb literally tons of force.
  5. The intent of a restraint system is to hold you in place during a crash. Don't skimp on belts or mounts--they could save your life. Remember this each time you work on or around your belts.

  1. SCORING AND JUDGING FOR INDIVIDUAL CHAMPIONSHIP

  1. Only registered drivers will earn points in Championship events.
  2. Any registered driver can earn points in any Championship events.
  3. If an entrant in a Championship event is not a registered driver, his/her position shall award no points. Registered drivers shall earn points as if all other entrants were also registered.
  4. Points will be scored as follows: First in class will receive points equal to the number of class entrants up to four entrants. Each succeeding position shall receive one less point, with a minimum of one point. Supplemental points for classes larger than four cars shall be awarded as follows: for each entrant in excess of three that any entrant beats, they shall be awarded an additional 0.1 point.
  5. examples:

  6. Entrants whose best times are equal will earn equal points. There will be no tie breakers (e.g.: two (2) drivers tied for first place in a class with four (4) cars will earn four (4) points each, the next fastest driver will earn three (3) points for third.
  7. Championship points may not be transferred between classes. An entrant who changes classes between events will earn points in each class.
  8. The total score of the individual season Championship will be based on the best 2/3rds of total Champ events, with all fractions rounded to the next higher number. In the event of a tie, the entrant with the higher total score wins. If the tie remains unbroken, both will be named co-winners.
  9. Individual and Team Championship standings will be maintained by a Standings Official to be named by the Council.
  10. Official results from each event shall be mailed to each participant, the Standings Official, and the DCSCC President no later than two (2) weeks after said event. Results should include DCSCC number, driver’s club, make of car, all timed runs with penalties indicated, trophy awards, and Team Championship points.
  11. If a Championship registrant is refused entry at a given event due to failure to comply with the sponsoring club's entry or safety requirements, no compensation can be given in the Championship standings. However, Council may grant one (1) point if entry is attempted and refused on the grounds of age or other circumstances beyond the driver's control.
  12. In the determination of final Championship Series position awards, drivers in a class must have entered a minimum of four (4) Championship events in that class to earn an award position.
  13. End-of-year awards will be given per the following schedule:

1-3 eligible entrants: 1 award

4-6 eligible entrants: 2 awards

7-9 eligible entrants: 3 awards

above 9 entrants: 1 award for every 3 (or portion thereof) entrants

 

  1. SCORING AND JUDGING FOR TEAM CHAMPIONSHIPS

  1. The Team Championship runs concurrently with individual Championships.
  2. Teams are set for the entire season except the Council may allow changes submitted, for good cause, IN WRITING.
  3. Teams consist of a maximum of five (5) drivers, each registered for the Individual Championship Series and from the same club.
  4. Teams must be submitted IN WRITING to the Standings Official before the first event the team enters.
  5. Clubs may enter any number of teams. Points cannot be transferred among teams.
  6. Scoring
  1. The team's score shall be the sum of its three (3) highest driver's scores.
  1. A driver's score for Team points shall be determined by the following system:

d:\dcscc\1998\book\pnts.xls

 

  1. Driver’s score is the point value from the table, less the individual’s difference in time behind the class winner, plus 10.
  2. Example: Winner’s time = 54, driver’s time = 52, second place in a class of 4 scores 3 points (2nd place) - (54-52) + 10 = 11 points for the driver score.
  3. Teams are arranged in descending order, the highest Team score being first.
  4. The first place team will receive points equal to the number of teams qualified in that event. Each succeeding position shall receive one (1) less point. Teams which have less than three (3) drivers at a given event earn no points for that event and are not counted as entrants. Example: if five teams have at least three members each (i.e., 5 teams are present), the second place team receives 4 points toward the team Championship.
  1. The Series Team Championship is the team with the highest points total at the end of the season. The number of events counted is the total number of Championship events held less One (1).
  2. End-of-year awards are given to the top three teams.
