Knowing that the 4 link is going to hook better and give more options on a second gen Camaro, is there any IHRA/NHRA benefit to running stock suspension? At our local tracks the car will be bracket raced in footbrake class with a drag radial tire, but I just wondered if I ever planned to run national level events would it be best to go ahead and spend the money on rear suspension now to ensure that the car will be best equipped later, or at that level is there a stock suspension class?
Thanks.
