Ok well ive searched for two days on google and here on the forums and all I managed to dig up was threads about ZR1 wheels and SS camaro on my thirdgens. Plus or minus confusing statements about offsets and wheel spacers vs adaptors...soooo

Either way, here is what I got.

82" Z28 Lowered.

My new rims are 93 Corvette 17x.8.5 +56mm and rears are 17x9.5 +56mm
Tires are Goodyear Eagle F1 GS-D3 255/45ZR17 and 285/40ZR17

Here is a picture of the rims if you dont know what they look like.

Mine happen to be chrome though.

What do I need to get in order to make these fit on my car and what will the difference in traction be compared to stock rim and cheap stock replacement tires....

 

Andris Skulte @ http://www.skulte.com/ will be able to help you. He also owns a third gen Z28.

 

Thanks,
I will try and get in contact with him and see what they say I need.
