Re: What stock GM wheels fit w/ No mods
Almost all of the wheels require you to trim the front axle shaft, to fit the center caps. The only wheel I can think of that might work with out it, is the 1988-1989 Corvette 17" wheels. I even suspect that you could use the stock SyTy center caps. You would need spacers to fit the rear flush. If you want no spacers but didn't mind cutting the front axle to shorten the ZR-1 wheel (3 style of 17x9.5 & 17 x 11 will fit front and rear and require no spacers. The rear will stick out a litte past the cladding, but its not bad at all. The Grandsport front (17 x8.5 or 17x9.5) and 17x11 rear will fit will out spacers and fit flush.
Another quick note is with the stock front suspsension the 17x9.5 will will the front arms if you turn the wheels fully. You can either deal with it, put stop on spindle of notch the arms. The 17x8.5 Gransport will will not do this, but its rare because they only came on GS convertible and their were only 190 of those made, plus what ever was sold over the GM parts counter (an trust me 17x8.5 weren't the most popular size to be sold)
