What is the thickness of the front rotors of a 931 with the 5-bolt setup ?
And when should they be replaced, i.e. minimum thickness ?
And the rear discs ? _________________ 931 1979 |

According to the little Technical Specification book when new they are 20.5mm (front) and 20.0 (rear). The "Minimum Brake disk thickness after reworking" is 19.1mm (front) and 19.2 (rear). _________________ 1979 924 (Gone to a better place)

Info is also hopefully stamped on the rotors themselves. . . _________________ Toofah King Bad
