I have a pair of these as a back up braking plan for my CSL
. Has anyone done this conversion before ? or does anyone know of someone that has ? They are the front callipers made by "BREMBO" as fitted to PORSCHE 928 S4, 944 Turbo, 968 Club Sport, 911s (1989 onwards non Turbo) and Boxter S, I think. Any advise, pointers, useful comments are more then welcomed
