18's Front 19's Back??
 

Anyone have this setup and some pics? I'm considering giving the Z a more aggressive stance by going one size larger in the rear. I don't imagine that would kill performance that much and would probably look hella sweet.

go with 20's on all four - my boy Cazz has 'em ans they are sweet. I'm changing my 18's because of it. Gives it a rougher look all the way around!
