Similar questions if the Oldsmobile were to move to J, would it be allowed to run at 12.50 (minimum J weight) even though the car comes in at 13.44?


Rules state that you can remove weight to the lightest possible weight for that class, so the minimum racing weight for K will be 13.00 x 232 = 3016 lbs + 170 driver allowance = 3186 lbs.

Rules also state that you can move one class down or one class up, so the other calculations from the tool show the minimum racing weights for J and L, calculated be multiplying the minimum power to weight factors for each of those classes by the power factor for the engine.


Can someone provide the page in the rulebook or a copy of the actual rules being referenced?


Thank you in advance for clarification and to Dwight for creating a database.

WEIGHT
All cars will be permitted to run on the class minimum weight, but
may be no heavier than the minimum for the next heavier class.
Car can move up (lighter) one class or down (heavier) one class. If
weight is added, must be properly attached; see BALLAST. Class
