9 inch wheels

Would trans am wheels that are 17x9 fit the grand prix

no.

gp's are 5x115 and can fit 5x114.3

When I said 17x 9 I meant 17 inch wheel 9 inch wide the bolt pattern on the trans am is the same as the gp

no, its not.

I'm sorry your right

its all good. GL on the wheel search. chaeck out bio's wheel article in suspension. Good stuff

GP's have 5x115 or 114.3.. Firebirds, Formulas, and TA's have 5 x 4.75 inch or 121mm.

I have a 95 Formula with Z06's and yeah I'd LOVE to put those rims on my GP but

Thanks for the info appriciated

5x120 is the bolt pattern...But adapters work

^^^ looks tits!

what size adapters? like width

About an inch was the thinnest the company I went with made them. Any less and you start to run into strength issues since you're basically bolting on a new set of lugs. Vette whees are already something like a 50ish offset IIRC, so you could run them with adapters and they would fit perfect.

I find some on ebay that are 20mm and they still adapter to a knew bolt pattern.

An inch is ~25mm so 20 is probably fine. I have heard of some eventually cracking though, not sure of why,but be careful where you buy them.

adapters have grown on me just because i could swap to 5x114.3 bolt pattern and my wheel options skyrockets, but i would always prefer the correct set of wheels over adapters.

Yea, the correct setup is always the best, good adapters are an alternative if you can't find what you want. Unless you're tracking the car a bunch, I'm not sure if any of the organizations like them.
