Tom,
Are those offset numbers for the C5 correct?
I thought they were 56mm front & 65mm rear?
I want to make sure I have the right info.
Thanks

The specs I listed came off Ronal's website. I know for fact the Z06 offsets listed are correct...relying on Ronal for the C5 numbers.

What you listed sounds like repro wheels that were made for an F-body fitment. Many repro Y2k and Z wheel mfr's are doing this.

A 2mm difference on the front is nearly nothing.
The 10mm difference out back tucks the wheels in about 3/8" more.

I could go measure my stock Y2k wheels and let you know for sure.
