Default difference between rims?

Does anyone know what the difference is (if any)between the zr1 five spokes and the grand sport five spokes? i've got chrome five spokes on my '89 but not sure exactly what they are

The difference is width and backspacing. GS front wheels are 9.5x17" with 56mm backspacing. GS rears are 11x17" with 50mm backspacing. Go to afswheels.com, shows what fits what, good repro wheels. :cheers:

I think the ZR1 rims are about 30mm backspacing, meaning that they would stick out further beyond the fender.

the ZR1 offset is 36mm. if your wheels are sticking out a little, you probably have 36mm. if they are tucked in nicely, you have 50mm.
