They will fit any vehicle with a 5 x 100mm bolt pattern. Beretta, Cavalier, Cimmaron, Grand Am, Skyhawk, PT Cruiser, Scion TC just to name a few. They will stand out a bit more on the FWD applications. I think the same wheel style from the Grand Am and Sunbird was a 43mm offset, or at least the same offset as the front wheels of the 88 GT and Formula.
On my first 85, I wanted lace wheels but couldn't find any at a reasonable price. When I was picking up the Isuzu transmission at a yard, I saw a pair of Oldsmobile lace wheels that were the same lug pattern and got them. They didn't have the 1 inch lip like the Fiero wheels, but they didn't scrub on turns.
