i have a set of ZR1 rims im putting on and am curious what size spacer is proper for the front wheels. i dont want the wheels sticking out too far, but also dont want them rubbing the sway bar when i turn. i've had ZR1 on the rear of the car at the track before, with 3" spacers and they worked fine. anyone that has experience with this please chime in.

 

In the 10+ years of TGO, this question has been answered a million (literally) times.

 

I have 96 ss rims on my 91 rs. It takes 2" wheel spacers to run them. The wheels are 17 x 10.5.

 

found a site that recommended 2" spacers specifically. but also gave how to measure and calculate offset/backspacing, and using a formula, determine required spacer. pretty neat site IMO.
and yes, i was just being lazy and asking when after searching 5 min i found this site. funny how i always get mad at those ppl... well, for anyone else with a common question, here ya go.

With a 4th gen rear, you won't need rear spacers though, at all.

Only with 4th gen wheels, would you be needing spacers on the front.
