'85 930 Front Rotors

[Arnage]

Can someone please tell me what the "new" and "replacement" ticknesses should be on an '85 930 front rotor. Thanks, Art

My workshop manual says 32mm front new and replacement 30mm. Maybe someone with more knowledge will chime in and confirm this?

Thanks Stephanie, but my calipers say the drilled rotors I have are 33.56mm thick. I am trying to determine if these are new or if they have been turned.

'85 930 front rotors are 32mm new and have a min thickness after symmetric machining of 30.6mm

rears are 28mm new and min 26.6mm

Thanks Bill. I guess I need to recheck my electronic calipers for accuracy.
