I run 930 calipers on our '75 Carrera race car. For the track I up graded to the Rennsport 993 front rotors shaved down to work with the 930 calipers. They worked great. A coupe of changes I made was to add a dual master cylinder set up for better brake balance. I was getting front lock up due to running 255 fronts & 315 rears. The front brake bias with the smaller tires was the issue. A good up grade for the rear would be C2 turbo calipers.
I kept the 930 calipers so I could run 15" wheels on the street, and 16" & 17" wheels at the track.
