i had the same issue the other day on my 8v, after a long wait getting the same bbs's refurbed and time to put them on they catch on the calipers badly so car wont move, was bemused as obviously vr6 brakes should be bigger. did you say you've solved the problem with 10mm spacers? i was thinking about getting 15mm for the fronts but wasnt sure what would be enough? just worried about rubbing on the arches, as im lowered on coilies..
