Its a decent finish and they were very easy to deal with, but there were a couple of little details which vexed me slightly. I would use them again, but not necessarily for Brembos as the price they quoted someone recently on a pair of S8 4 pots was a bit crazy.
I think Pro Calipers are the forum-preferred caliper specialists. Personally I probably wouldn't go to them for a cosmetic refinish since they powder-coat, not wet paint. I despise powder coat. Its a cheap bodge instead of a proper paint system and it doesn't last anything like as long. Ever seen a powder-coated boat? No

They do seem to do a good mechanical refinish though.
BCS get some pretty bad reviews - I think at least one forum member has had problems with them. They do paint though instead of powder. Dilemma
I'll just do 'em myself I guess
