I know you need the BMW bolt pattern, but other than that what are the specs?

Fronts are 8.5" and backs are 10".....

Fit??

Pics?

With proper spacers they fit.Pics of mine:

Wow! Ok, please give me the scoop.... Are those four BMW spec 18x10's?? Also, what spacers are you using? Tire size? Thanks again.

5 series spec is what you need, ETs around 20

All 18x10, right?

yes

That's looking pretty good.

whats the width of the front and rear? rear is 10 right? what about the front. and whats the off set?

front 8.5x18 et13 245/40R18 GY gsd3
rear 10x18 et28 285/35R18 GY gsd3

Sounds like those wheels are going to be tucked in quite a bit. Make sure to test fit them for inner wheel well clearance.

Z28 Jeri, What model year BMW did these wheels come off? Does your IROC have a stock 3-gen rear? Was it nessasary to use any spacers? And what does ET in the tire size mean?...is that the back spacing in metric? Thanks in advance, Steve.
