Reviews of Centric brake caliper

The Audi Girling 60 pistons are 45 & 40 mm and 13lb with the brackets ea side. The VW R32 single piston brakes are 54mm and 11 lb without the brackets ea side # (Centric 146.60009 ). If you decide to go with the dual piston R32 calipers 1J0 615 123 E (left) 1J0 614 123 E (right) they are the same one used on the 95-01 BMW 750il. The rebuild parts are the same of course but half the cost (BMW part # 34111163316) @ $40 vs. VW @ $80. The BMW caliper part #'s are 34111163317/8. Have a go at this link on the BimmerForums. They guy even had them powder coated R32 blue! They're about $47 rebuilt per side http://forums.bimmerforums.com/forum/showthread.php?1895063-DIY-gt-750-Brake-upgrade-rebuild I did not check on the compatibility of the brake brackets though. BMW part # is 34111163319/20. VW part is 1J0615125/1J0615125B pictured in jumbotron size.
