2) The bodywork as viewed from the side and above must cover all mechanical components except that the in­ take, exhaust and radiators may be exposed.

The bodywork must extend over the full width of the tires for at least one third (1/3) of their circumference as viewed from the side.

The tires shall not be seen as viewed from above, although the rear tires may be exposed as viewed from the rear. Ventilation slots are permitted. Cycle type fenders (which only cover the tire and are not con­ tinuous with the rest of the body) are prohibited.

-19-

All elements of the bodywork shall be completely and neatly designed and finished with no temporary or makeshift elements and shall provide comfort and safe­ ty for the driver.

3) Aerodynamic devices must comply with the rules relat­ ing to bodywork, must be securely mounted on the entirely sprung part of the car and not be moveable when the car is in motion.

The following rules are intended to prevent cars from having their ground effects enhanced by maintaining a seal between the bottom of the bodywork and the ground.

If more fuel is needed, the car must return to the race course and complete at least one lap before stopping again to refuel. If the fuel cell requires venting during refueling, a fuel vent container with a dry-brake coupling or a discriminator valve (ATL) must be used. The 11 gallon refueling can must be hand held by a person standing on the ground (not on the pit wall, rail, or other elevation.) Fuel transfer must be by gravity only and shall not be assisted by vacuum or pressure.

The person handling the fuel container may take a position close to the pit wall or rail immediately prior to the car arriving for its refueling stop, but shall not step out or cross in front of the approaching car until it has come to a complete stop.

The refueling crew must wear fire-resistant outer clothing which covers the body from neck to ankles and wrists, whenever fuel is added to the car while in the pit lane during practice and qualifying.

9. MISCELLANEOUS

A. There will be a mandatory driver/entrant meeting at each event. Roll call will be taken and non-attendance will result in m andatory fines.

B. All crew members must be attired in clean, matching uniforms at all times during practice, qualifying, and the race. Crew members not properly attired will not be permitted to enter the pit area.

C. The Professional Racing Staff working the pit lane are "Judges of Fact" regarding the legality of Can-Am pit stops. Their decision is final and cannot be protested.

D. All Can-Am competitors (entrants, drivers, team manag­ ers, crew chiefs, and mechanics) whose duties require their presence on the trackside of the pit wall, must wear a Can- Am competitors picture pass during practice, qualifying, and the race. To qualify for this pass, the competitor must hold an FIA Driver or Entrant License issued by their ASN or be a full member of SCCA or CASC.

E. Upon completion of the race NO fuel shall be added, tires changed, or other work performed on cars to be impounded without specific approval of the Can-Am Series Technical Administrator or his designated representative.

F. Engine displacement checks may be made randomly among the competitors. Not necessarily those who finish in the first three!

G. The Can-Am format is based upon pit stops for all compet­ itive cars. In order to complete the race distance, cars of over two (2) liter displacement must make at least one (1) pit stop in a 120 (approx.) mile race, two (2) pit stops in a 150 (approx.) mile race, and th ree (3) pit stops in a 175 (approx.) mile race.

AUTHORIZED MODIFICATIONS

A. G eneral

1) It is not permitted to make any changes, alterations or modifications to the standard automobile or any com­ ponent as produced by the manufacturer, unless such modifications are required under safety equipment or specificaily authorized by these rules.

Any springs (including torsion bars) on the automobiie such as clutch, suspension, etc., may be replaced by others of unrestricted origin, but with no change in the number provided by the manufacturer and on condition they can be fitted without alteration of the original supports or attachments, except as specifically autho­ rized by these Rules.

Where alternate suspension and drive train equipment is authorized, modifications to the car/chassis are permit­ ted to install authorized equipment, provided the mod­ ifications serve no other purpose.

-37- B. Chassis and Bodywork

The intent of the following rules is to maintain the recognizable external features of the manufacturers make and model while providing the necessary safety and per­ formance modifications. The restrictions regarding the external shape of the body and the use of belly pans is intended to prevent unauthorized attempts to obtain a ground effect by provisions in the rules which permit one- off chassis and frames. The provisions were made to reduce the cost of building and repairing a Trans-Am car...not to bring in high technology streamlining and/or ground effects.

1) The external shape of the body cannot be changed except when specifically authorized i.e., fenders, front and rear spoilers and authorized alternate hoods. Stan­ dard grilles, window moldings, rain gutters, and all external trim and model identification or approved facsimiles must be retained.

2) Component parts of the bodywork such as hood, doors and deck lid may be lightened or replaced by ones made of alternate material provided the shape is identical to the original part or approved alternate.

3) The orginal roof, windshield and angle of the windshield 1 must be maintained.

5) The headlight openings must be covered with a wire mesh screen or panel made of metal, fiberglass or other approved material having the same contour as the original lens, mounted so that the headlight bezel/rim remains in place maintaining the standard appearance of the production automobile.

Other tires may be listed as they meet SCCA approval requirements which may include performance testing. Tires used under "WET" track conditions are not specified.

"At both road course and oval track events the tire compound used to start the race may differ from the compound used during qualifying as long as both the qualifying and race compounds are on the approved tire list for the appropriate track".

This rule is subject to change if more than one make of tire is approved for Super Vee competition.

-70- 8. OVAL TRACK PROCEDURES

A. Practice

1) During practice sessions, all cars must enter the pit area and stop at their pit at their first opportunity after observing a yellow light at any light station on the track. No car may re-enter the track from the pit lane until the yellow light situation is solved and the course becomes green again.

2) The scheduled time allotted to practice is total running clock time, not on-track green flag time.

B. Q ualification

1) Cars will qualify in the order in which they are lined up in designated position. These positions are reserved as long as the car remains in the designated place until the entrant is ordered to make his qualifying attempt.

2) If an entrant does not proceed with the qualification at­ tempt when ordered to do so, he will forfeit his position in the qualification order and he may be penalized further by the loss of one qualifying lap.

3) If qualification is suspended for a considerable period of time, entrants are not required to maintain their car in the designated place provided the car is returned to position within the announced time period. Any suspen­ sion of qualifying will be announced as well as the designated time at which ail cars must be returned to the qualifying line up.

U) An officially entered back-up car may be qualified, but shall only start the race in the position in which it qualified and it must be driven by the driver who qualified it. However, a car or driver, not qualifying, may start at the rear of the grid at the Series Chief Steward's discretion.

5) A qualifying attempt shall be considered started when the front wheels of the car cross the starting line after the qualifying start signal is given by the starter.

6) The number of warm-up laps will be indicated by the Series Chief Steward at the Qualifying Briefing. If the car stops anywhere on the course before the qualifying start signal is given by the starter, the driver will not be charged with a qualifying attempt.

-71- 7) If the car stops anywhere on the course after the qualifying start signal is given by the starter, the driver will be charged with an attempt. Time permitting, those cars having started a qualifying attempt, but unable to complete the attempt, will be permitted to begin a second qualifying attempt. First priority for a second qualifying attempt will go to cars that failed to receive an^ qualifying time during their first attempt.

8) In the event qualification cannot be held or completed prior to the start of an event, the field or remaining field will be filled by means of a seeded lottery by those drivers who have entered, but who have not qualified. Details of this drawing for positions in a specific portion of the starting grid will be announced prior to the drawing.

C. S tart

1) Leave start/finish with pace car;

2) Cross start/finish first time with pace car;

3) Cross start/finish line second time with pace car;

5) Pole car brings field gradually up to speed for possible start third time by start/finish;

6) Cars may not improve position prior to crossing star^ finish line; (Pulling parallel to car in front of you is improving position — penalty of a fine.)

7) Passing prior to crossing start/finish line -- PENALTY OF ONE LAP.

D. Yellow Light/Flag Condition

1) Lead car is responsible for controlling field. Get field to slow down with discretion — hands in air. Do not follow safety car too closely. Leave it sufficient room to drop down toward pit entry after its light is ex­ tinguished.

2) In case of pass in progress when light goes on, over­ taking car is expected to fall back and take station behind car he was attempting to pass.

-72- 3) AU confirmed reports of a pass under yellow will result in an immediate ONE LAP PENALTY. (Further penalty may be assessed.)

Ï) Responsibility to mitigate or defend propriety of the pass will rest with the offending driver, not offended driver or officials.
