I know when my wife had a tire issue we used one of my spare stock wheel/tire combo to get her 2004 to the shop.

I'll be trying her old rears on my car to see if there are any issues. I need to get another set of track wheels and old C5 take offs are pretty inexpensive. If I can go 18" then my tire choices get a lot better as well.

Base C5 17x8.5 and 18x9.5 wheels are a direct fit on 88-96 C4 Vette's.

84-87 C4 Vette's require spacers.

Huh????
My wife's 2004 uses the same size lug nuts as my 92.

You may want to get matching lug nuts for any C5 rim you use. But you won't need to put in new Studs.
When I do it I'll use the same open lug nuts just because they will be track wheels only.

Thanks again all! I went ahead and bought 01 c5 base thinspokes. Now I am trying to find some reasonable hubcentric 10 mm spacers to position the rear wheels properly.
