any rim that fits a 94-04 car will fit with the 95 spindles you have, so a 17x9 or 18x9 bullit wheel (or fr500, or whatever) will work just fine, although if you have a pre-91 car you may want to stick with an 8" wide wheeel (fenders changed to accomadate the 16" ponys in 90 or 91, its hit or miss on if earlier cars will rub with the wider wheels at full lock).
if you REALLY want to go 20's (please dont for the love of god, but its your car), the same rules should apply, just make sure to not use a tire too big and it will fit.
