First off I have a 1991 Pontiac Trans AM GTA. Im picking up a set of 4th gen camaro zr1 wheels size 17x9.5. I tried searching for my info but couldnt find it. Ill list my questions so it will be easier to read. Thanks for all you help in advance.

1. Will these directly fit my car?
2. If not, what do I need to make these fit? Links would be great.
3. If I upgrade to 17x11 what will I need then or will it be the same? Edit...They are 2- 17"x11" (+36.5mm). The wheels are 5-lug (5x4.75). I found a set of these what will I need to make these fit?
4. Will both wheel combos fit with eibach Pro Kit?
5. Whats the widest rear tire combo for both sets?
6. Lastly, Anybody have pics of this combo on a 91-92?

Thanks so much for all your help.

I can only partly answer on the fitment.You will need spacers front and rear for correct setup.Of course the correct lugs but make sure these will work with your spare.if not then bag 5 of your current lugs and zip tie them to your spare.

this has been discussed many times - hit the search key. - spacers required at both ends, no mattter which size you run in the rear. 315/35/17 fits on 17x11, will work fine w/ your pro-kit and the proper spacers. I'm sitting lower than the pro-kit and have no issues...
