I just got my GS and would like to buy some wheels. I really want to get something that looks good and that i can tuck. So the question is what offset is good for the rear on 18's or 19's?

Thanks
I will have some pics up soon.

 

18's or 19's won't matter, what will matter is the width, and the amount of fender rolling/pulling you want to do. and how flush you want to sit.
