P1 Class Weight Change Proposal
#32487 from Ralph Firman · Not recommended · Minutes (2022-06 Fastrack)
Thank you for your letter. The Club Racing Board does not recommend this change. The proposed RDRF car's actual weight with
a Halo device is presently unknown and when completed could conceivably meet the current minimum weight under whichever
spec line the car is intended to run without the requested 30 lb. increase. Also, a need for an across-the-board 30 lb. increase
has not been demonstrated because no existing P1 car uses a Halo device and no P1 competitor has expressed a desire to
retrofit an existing car with a Halo device, so the requested increase would penalize all other cars in the class with no factual
basis for doing so. In addition, the fact that adding a Halo device would result in a higher center of gravity provides no basis for a
Balance of Performance adjustment under the P1 class philosophy. BoP adjustments are not used in P1 to compensate for
chassis design choices, including ones that might result in a higher center of gravity. Weight is added or subtracted (or restrictor

size reduced or increased) based solely upon a car's longitudinal acceleration rate in a speed range of approximately 60 to 100
mph, which would not likely be affected by a higher center of gravity.
