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 ?

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).

Info is also hopefully stamped on the rotors themselves. . .
