So I go to fit my new 19" BBS CH's this weekend and I find they're totally the wrong offset, they're et50, balls. So I'm looking for some spacers, H&R seem the way to go, after trial fitting a couple of different thickness mock ups I'm gonna need a least 15mm, I think! However they sell 20mm bolt on hubsentric adaptors, gonna be cheaper than buying spacers and extended bolts. Are 20mm spacers gonna be too big on my S4, anyone have any idea? Come up against the same problem?
