Vette suspension in nova

i dont agree that moving the trailingarms will affect the hit of the car like moving the arem on a 4 link.. and the reason fro this is that the trailing arms mount to the uprights and they do not absorb any of the forces involved in turning the wheels.. that reaction is handled by the longitudinal arm mounted to the diff case... the trailing arms only handle thrust from the wheels on acceleration and enginebraking, and the rotational forces excerted when applying the brakes..

I do agree that you don't alter the tire loading effects caused by the rotational forces of the rear end by moving the front of the IRS 4-link, but you do change the instant center of the rear suspension. This alters the percentage of loading caused by mass of the vehicle on the rear tires during acceleration. Some circle track cars use this principle (moving the 4-link pick-up) to load the outside rear tire during acceleration. Most use a full floating rear end which, in effect, stops the rotational forces from transfering through the four link, much like an IRS.
