3. All tires, except foam, can be used, except where specified by class rules.
4. Cars should have all 4 tires touching the track or the wheels and axles must be of original equipment or stock replacement. Solid front axles may replace stub axles in all classes.
5. Tires must fit under the car completely when viewed from above, or be in the stock position.
6. All cars must have numbers in three places.
7. All cars must have interiors and drivers similar to RTR manufacturer. If car came with full interior, then it must race with one (in MSP and Super Touring, interior may be trimmed slightly to accommodate motor and/or magnet upgrades as allowed, but still must be present and covering the inside of the car to the same degree as from the manufacturer). All cars must retain the “glass” as provided by manufacturer.
8. Painting and detailing are allowed in all classes.
9. Weight may be added in any amount and in any manner, but must be dead weight. Weight added must be inside/topside of chassis and chassis cannot be modified in any way to accommodate the adding of weight.

Axle shims may be added. Any lubes and cleaners may be applied anywhere but must not be allowed to get on the track.
12. Resin and hard shell plastic bodies (e.g. model kits) may be used so long as they are approximately the same weight as the original and cover the chassis to same degree as if from factory. Original interior type must be maintained as defined above. Determination of tires and wheels will follow the manufacture of the original/donor chassis if stock wheels and tires are required by class rules. Chassis so rebodied must be from a car that is legal in the class where the rebodied car will be raced. Chassis may be trimmed around the periphery only enough to allow
fitting to the body.
