allowed. Trackside adjustable wheelbase is not allowed (can’t have toe blocks or anything else attached to an
easily adjustable mechanism to allow for wheelbase change trackside). Left rear can be toed in via toe block.

Offset- Right side of the cage can be no further offset from the outside of the RR tire than 3.625”
Ballast Weight- Brass, tungsten or steel hubs, arms, arm inserts, caster blocks, steering arms are not allowed.
Ballast weight can be attached to the main chassis area is allowed as long as it’s secured properly.

be full gears. No narrowed or lightened gears allowed. Plastic, Aluminum and Steel gears are permitted.
Steel outdrives only. Blades are permitted. No gear diffs allowed. No rear motor cars allowed unless you
can do it in a manner that the tail tank is appropriately sized and located.
Solid Axle Option- If a solid rear axle design is used it, the motor must be mounted to the chassis and cva/cvd
must be used to drive the rear axle. No belts or chains will be allowed. A spur gear and pinion must be used
in conjunction with the motor plate mounted to the chassis.

Cage – Must have a scale appearing contemporary cage made out of rounded stock. The cage must be
symmetrical left to right and mounted level to the chassis. Unrealistic shaped cages designed to exploit the
rules below are not permitted. Maximum cage width at driver halo, down tubes, and top frame rail: 3.600".
Minimum cage height is 6.00” while maximum cage height 6.25" from top of chassis to top of cage at highest
point. Rear “down tubes” must slant forward. All cage and body components such as cage, bumpers, nerf bars,
Page 18
hoods, side panels, tanks, etc. must be mounted on the centerline of the cage. Chassis may not extend outside
of the side panels by more than 1/4" on either side.

Maximum height of front bumper is 1.5” from the bottom of the lowest point of the chassis. Scale appearing
side nerf bars must be used on both sides of the car. A scale appearing rear hoop style bumper must be used.
Bumpers and nerf bars must be made of rounded stock with no sharp edges.

rectangle (Swindell) style rear tank is allowed but must have a proper style rear bumper to go with it. You can
not simply have a flat tail section with no bumper.
Headers - Three dimensional scale appearing headers must be used on the left side of car in “engine area”.
Material must be plastic or aluminum. Not allowed to make inserts for these to add ballast weight.
Side panels – Flat side panels may be made from molded or fabricated polycarbonate. Maximum height of side
panels in front of the driver cockpit is 4.50" from the bottom of the chassis. Must have minimum of 1/2" high by
2.5" long openings on both sides of cage in driver compartment. Additional material may be used/added to
either side of the side panel openings to replicate a scale appearing driver but may not exceed 1" x 1". Side
panels may not extend beyond the cage by more than 0.25" Side Panels may not extend into the area that is
behind the rear axle AND below the top of the rear nerf bar. Scale appearing driver arm guards and engine
vents may be used but cannot extend more than 3/8* from the side panels. No other flares or turnouts
designed to deflect, trap and/or form a pattern for air to travel in a directed manner are permitted except for
those used to cool electronics.
Hood – A scale appearing hood must be used and is defined as beginning at the point where torsion tubes or
cross brace would be on a 1:1 car behind the front bumper. The hood must be tall enough and wide enough to
allow room for a scale engine intake and air cleaners (no unrealistically low or flat hoods). Minimum vertical
gap from top of hood to bottom of front cage crossbar.
Nose Area – No molded or fabricated nose piece may be used and is defined from the torsion tube or cross
brace would be on a 1:1 car. You are not allowed to have anything below that point that is on the same plane
as the hood. No scoops or bodywork allowed in this area. You can have side panels along the front of the cage
but they are not allowed to stick past the cage sides.
Extra Panels - No molded or fabricated scoops, wings, or extra panels can be added to the car to create
downforce. The panel in the cockpit area that is used on full size cars at the Chili Bowl is not legal.
All height measurements are from bottom of chassis unless otherwise noted.
General - Maximum Overall Length: 16.750". Maximum Chassis width: 4.2" Maximum of 4 shocks can be
