I believe the ZR-1 will bolt right on and clear, meaning they shouldn't rub anywhere... but I do believe the 11in ZR-1 rims will stick out just a hair wider on the GS due to the different offset...

Someone chime in if I have that incorrect

...post some pics of the GS when you get it, those cars are awesome :fahne:

Pretty sure ZR-1 rears are 38mm offset, GS are 55mm, a difference of 13mm. (.51 inch)

Be very careful with ZR-1 rears on a GS. One nice bump and you?ll crack a fender or both. Ask me how I know!

I agree with Mark on this and have seen the outcome. Perhaps you could temporarily adjust the rear spring bolts. It will get you just a little additional clearance on stock bolts but even a smidge could help.
