Re: C6 Grand Sport wheels?
I really don't know the dimensions of the GS vs the C6Z wheel. I just know that when I got my C6Z, I removed the rear wheels off each car and tried to swap them. The C6Z wheel fit on my C5Z but stuck out.
I'm too lazy to search for wheel dimensions. I'll leave that to you.
I tried to find my pics that I took when I did the swap but for some reason, I can't find them. Had 2 computers crash on me last year and had to replace them both. I hope I didn't lose the pics.
LS2 + LS6 + LS7 = LS15.
