RULEBOOKRULEBOOK

BODIES
Stock appearing bodies only.  No wedge bodies or wedge noses. No flat sided slab bodies.  Five Star stock appearing ABC style bodies are the only approved bodies for this series.  The bodies must meet Five Star specifications for lengths, widths and heights used.  The left side door must be within 2” of the door bars.  Aluminum or steel sides may be used as long as they conform to Five Star original specifications.  If you have any question about configurations, please call first.

CHASSIS CONSTRUCTION
The only approved front clip is a 1970-1/2 to 1981 Camaro/Firebird GM F car sub frame.  This frame must remain stock unaltered except the cross member can be cut for the fuel pump and oil pan clearance.  The upper A-arms can be moved to accept the approved upper A-arms.  The lower pickup points for the lower A-arm must remain stock unaltered.  The rear part of the frame can be cut to mate to the fabricated frame but cannot be cut forward of where the frame curves down at the rear.  Simply you can cut the rear unibody supports but cannot cut forward of where the frame starts to curve upwards.  The frame must remain stock from that point forwards.  The spring pockets can be boxed in if coil overs are used.  Stock front clip must be a minimum of .100” thick.  Stock front clip must be maintained as manufactured.  Clip can be cut forward of front steering box and idler armholes.  The rear of the clip must remain stock to the bottom side of the rear rails.  Clip may be notched for oil pan clearance and for the fuel pump only.  Only one side of the cross member may be notched.  If you notch the top, the bottom must remain stock untouched, or vice versa.  Stock lower A-arms location must remain unaltered.  Lower A-arms must match year and make of clip used. Top upper A-arm mount may be relocated to accept tubular upper A-arms.  The clip may be boxed to stiffen the spring pocket if conventional coils are used, or you may box over the opening if coil overs are used.  Jacking bolts are allowed.  The frame may be notched for coil over or shock clearance.

108” wheel base minimum, 109” maximum.  Fabricated frames are allowed from the front clip back.

All other interior sheet metal can be either steel or aluminum. 

Driver compartment must be completely sealed off from the underside of the car. Left side frame rail is defined as the outermost left side rail and the right side is the outermost right side frame rail.

Chassis may be constructed as a straight rail or of perimeter design.  Both the right and left frame rail must run parallel to the centreline of the car.  The left side must kick out to run parallel to the left side door bars and then kick inwards to the centreline and tie the front and rear clip together.  This frame rail must be within 7” of the outside of the left door bars and be a minimum of 64” long.  The right side frame rail must run straight to connect the stock right side frame rail and the rear clip or be of perimeter design and extend out towards the right of the car.  The right side frame rail cannot extend to the left past the inside of the stock right side clip.  Minimum width of the frame measured from the outside rail of the stock front clip on the right side, the frame width must be a minimum of 49” measured to the outside of the left rail.

On the main roll cage the dash bar and the bar behind the seat that connect the left and right roll cage together must extend full length and be a minimum 1.75” od  X .095 thick tubing.  The cage must also have a bar extending from the dash bar to the top of the cage at the front located in the middle, left to right, and be 1.5” X .065 minimum.  Three right side door bars or an X in place of the door bars must be used and constructed of 1.75” X .095 tubing. Door bars must be plated with a minimum .060 steel plate on the bottom 3 door bars down to the frame and extend the full width of the roll cage.  The steel plate must also extend forward past the drivers feet and tie into the frame rail and the mandatory 1.75” X .095 tube that protect the driver’s feet.

Interior sheet metal must be of open cockpit design.  No boxed in cabs.  The interior must be built so as not to direct wind in an advantageous manner.  The interior must be constructed as follows:

WEIGHT
All cars must weight 3100 lbs. Fuel can be added after the race to meet weight requirements.  All weights are with the driver and full of fuel.*WEIGHT RULES WILL BE STRICTLY ENFORCED* Cars will be weighed after the race and must meet posted weights.  There will be no provisions for fuel burned during the race, however fuel can be added after the race to bring the car up to total weight if need be. If you think you will be underweight, please be prepared to add fuel. Do not add weight or add fuel to the car until instructed to do so by the tech man. Only one crew member per car will be allowed in the tech area after the race.  Only that one person is allowed to add fuel to the car.  That one crew member may also observe the scale weights of their car only.  Once your car is weighed, you must leave the scaling area. Your car may be detained for further inspection after it is weighed.  The penalty for not meeting the weight requirements, total left to right and front, to rear will be the loss of points and money for the night. If any one is caught adding weight other than fuel to the car the penalty will be loss of points and money for that night plus all points earned in the year to that point.  If your car is involved in a wreck and parts are missing a provision will be allowed for that, but is at the tech mans discretion.

SAFETY
Seat belts can be a maximum of 3 years old. (Highly recommend replacement after 2 years.)  Roll bar padding must be used around any bar that the drivers head can come in contact with.

TECHNICAL INSPECTION
The tech team (Kevin or Ted) has the right to inspect any car at any time before, after, or during the racing event. If you refuse technical inspection or abuse the officials you will simply be disqualified, fined and or suspended.  Verbal abuse of racing officials will not be tolerated. The purpose of these rules is not to disqualify anyone.  In fact, it is just the opposite.  All cars should be as equal as possible so performance is based on driver and crew, not superior equipment.

If you have, any questions call TED ZERBIN @ (250) 477-8444 for clarification.  Remember it is a lot easier to get approval before you build, rather than show up at the track with a car that doesn’t fit the rules and not be allowed to race.

ANY CARS FOUND ILLEGAL DURING ANY OF THE NIGHTS EVENTS, WILL AT A MINIMUM FACE LOSS OF ALL POINTS, AND MONEY FOR THE EVENT. ADDITIONAL PENALTIES MAY ALSO BE ASSESED INCLUDING  MONETARY FINES AND ADDITIONAL POINTS LOSS.
