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.
