a friend of mine has some 93 formula rims (the three spoke curved ones) for sale.. he's selling them for cheap, and as far as I know they're in good shape, so I was thinking about buying them and putting them on my firebird.. it's a white 91 firebird with the newer ground effects.. think that'd look ok on my car? and, I'd need spacers, right? oh, one more thing, are the 4th gen wheels lighter than ours, generally speaking? thanks..
