I want to know what the front and rear rotor minimum thickness is on an 86 944 N/A.

thanks for your help!

There are two minimum thicknesses used. They should both be stamped on the rotor or hat. There is a minimum useable thickness at which time you should get new rotors, and a minimum thickness where Porsches says no more turning. Of course Porsche recommends replacing the rotoras rather than turning. I am at work and don't have my shop manuals with me. I will try to find the numbers later for you.
