Could you clarify that more?
Are you looking to put factory C4 ZR-1 rims on your car or are you looking for a recommended C5 wheel size to put a ZR-1 replica wheel on your car?
The factory size was what it was, you won't be able to pick them up with different offsets just because that offset will fit your C5.

The C4 ZR1 and C4 Grand Sport used the same AMold wheel design with different offsets. The GS didn't have the wide rear end the ZR1s had. What you want to order is the wheels with the C4 Grand Sport Offset. If you get them with the ZR1 offset the rear wheels will stick out of the wheel wells quite a bit. With the GS offset they only stick out about a 1/2 inch. I bought my GS offset wheels from AFS and had them painted grey (the ZR1 color) Vs black (the GS color).
I ran the 17x11 on all 4 corners of my 03Z. The fronts stuck out quite a bit but the largest problem with using that size on the front was the inside of the wheel hitting my DRM brake ducts and on tight turns in the garage the wheel would hit the lower control arm and the wheel weights would get stripped off.
The repro wheel manufacturers have modded the wheel design over the years to morph it into a Camaro wheel. The big difference is in the lug nut area. The Corvette wheels have a very deep dish while the Camaro wheels have the dish filled in. Thus the Camaro wheels have deep narrow holes for the lug nuts while the Corvette wheels don't. The deep lug nut holes can be a problem with some wrenches.

is it 50 MM offset? I get a bit confused between backspacing and offset. and tend to use backspacing to make it easier to meausre
sorry for the confusion. I'm hoping they make a 5 spoke zr1 replica wheel to fit a C5 Z06 that fit right
