I'm not sure what the proper formula for calculating this is, but will the following wheel size properly fit the FC without spacers? 16x7 +35 5x114.3

+35 to +40 should fit fine with a 7 inch rim with no spacers

Thanks! https://www.nopistons.com/forums/pub...IR#>/bigok.gif

incase you needed to know, the way it is measured is how far from the centerline of the rim the mounting base is offset.. Does that make sense.. ? https://www.nopistons.com/forums/pub...1047683561.gif if not checck tirerack.com for a better explaination..

Okay, try this. Will 17 X 7 5-114.3 fit on a 1987 GXL without modifying anything?

Depends on the offset.

I have 17x7, 114.3, +38 and they fit fine... would look better with some spacers in the rear though.
