what is the minimum rotor thickness for 991 3.4?
I know its on the rotor somewhere - looked and I don't see it.
I took a few measurements and rounding down in the interest of safety my fronts are 27 mm at 24k miles - no tracking.
Hopefully someone has the actual specs for original thickness and minimum thickness?? Pads are going on ASAP, and I need to determine if rotors are needed too.
Thanks,
DRP

I have always judged rotor wear by excessive grooving, cracks that connect two holes together or go to the edge or if they are warped (brakes shudder, but warping can be confused with pad build up). But I track the car frequently and am on my 5th set of pads and second set of rotors at around 11,000 mile.
If it were me, I would just change the pads if the brakes are still smooth and I did not see any damage to the rotors. If I could feel ridges or indentations from pad wear, I would just change them. OEM rotors and pads are not that expensive and a mm either way probably won't matters if you can get 24,000 miles out of a set of brake pads.
