Going to look at a set of Amer. Racing wheels tomorrow off a 98 or 99 Grand Prix GT.
Should these fit my 98 V6 Firebird withouit any problems?
I've read something here in the past about a double lip wheel if I recall correct.
They are asking $800. I'm thinking $500. if they fit.

If they fit a 97+ Grand Prix, they won't fit on your Firebird. The lug spacing is not the same.

This chart shows the bolt circles for various Pontiac wheels. The Grand Prix is 5 x 115mm, the 3rd and 4th Gen Firebirds are 5 x 4.75" (120.65mm).

Thanks for the reply. As I looked them over I found the 115mm on the back side and realized they won't fit. What is GM thinking making these different sizes on same year vehicles, geesh.
