biggest widest wheel and tire combo for 96 gt

[Unit 5302]

With a stock suspension and no quad shocks you most likely experiance major wheelhop off the line.

If you do some minimal suspension enhancements like rear lower control arms and like you stated lower it, the problem will be non-existant.

Oh, the Kenne Bell Stalker project car used 275/40ZR17's up front and 315/35ZR 17's out back on 17x9.5 and 17x10.0 rims.
