IF it werent for the 17 x 9 inch wheels on the SS/WS6, Id say
let all regular torsen rear end (ie stock) 99+, and
regular auburn rear end (98s) run Fstock.
but I think the 17 x 9s can give an advantage over
the 16 x 8 that is stock on the camarobirds.
how about allow them to run the 16 x 8s the regular cars use?
BTW, the stock WS6/SS have springs that lower it about .25 inch,
which will allow one to get more camber than a regular Z28/firechicken.
Also, the airbox itself on the WS6 has a larger opening (I agree ram air does
help in autox), so it allows the engine to suck more air, even at low speeds.
Just my opinion (sorry Ken)
