I have 4 Bonneville rims, 235/55R17 that I have off of my parts car.
Their bolt pattern is 5x115 and as we all know, the Fiero is 5x100.
I have purchased some 5x100 hub to 5x115 wheel adapters, and they are 1 inch wide.
Using this chart,
and this website, http://mcgrefer.com/sizeinfo/2355517
I learned that the wheel is 9.5" wide, which would put it near the bottom of that chart.
What I don't know is the offset of the rims, coupled with the one inch spacer, is how far would these rims stick past the fender?
Or would they rub on the strut?
I don't mind a little sticking past the fender, but obviously it can't stick out too far and be legal or look good.
Any ideas of these rims would fit?
(I haven't had a chance to test fit them yet)
