I've spent the last couple of days trolling ebay looking at calipers cause I got an urge to rebuild a set. After looking at hundreds of different makes and models of calipers with different mountings, different condition and different sizes. This got me thinking, apart from the B6 calipers, porsche boxster and S3/TT carriers. What other options are there for the B5 and has any one put any thing completely different on to a B5? I noticed A8s do a 380mm front disk. And there is some other makes of calipers on ebay that seems pretty cheap.
