I really love the CSL wheels on the Z4 and i'm considering it for my 1st upgrade along with PS2's, but has anyone actually tried the equivalent BBS wheel in 18" rather than the CSL 19"? It should be a tad lighter than the 19 so if anything should make a bigger difference over the standard wheel with Conti;s.
What do you think or should I just shut up and fit the 19's?
