Roll Couple Distribution and Other Numbers
Roll Couple Distribution and Other Numbers
(OP)
Is anybody familiar with typical numbers for roll couple distribution, wheel rates, and ARB stiffness for V8 road race cars (SCCA Trans-Am, GT-1, World Challenge). I've got an older GT-1 car that I've measured up and input into SusProg3D and want to check to see if the car setup is in the ballpark.
The corner weights are (673/659, 698/626). Spring wheel rates are 324lbs/in front, 104lbs/in rear. ARB rates in roll are 89 lb/in front, 65 lb/in rear. Weight transfer is 436 lb front/314 lb rear. Roll couple distribution is 69% front. Suspension frequency is 123 cpm front/83 cpm rear.
