You might have better luck with this question in the C5 forum. Just cut and paste it over there. Good luck.

How's this?
The rears fit from Corvettes 88 up and the rears fit 84-87 with a 1" wheel spacer.
I think 36mm offset

9.5" & 63MM

FYI late C4 is 56MM Early is like 38MM

There is a whole chart of this info in the FAQ sticky.

Update: The Tech FAQ has the right info


C5 base 8.5" 56mm
9.5" 65mm

Z06 9.5" 54mm
10.5" 58mm

18x9.5 on a 56mm offset. I think I know what you are getting at and I already did it. I run the 18" C5 wagon wheels on all four corners without a problem. If you keep the original C5 tire sizes then your speedo is off 4%.
