Rotor Wear - What is the correct Measurement?

[skymast]

What is the thickness (or lack thereof) point for when the rotors need to be changed. Thx

Carrera (not GT3 or TT)

Brake disc thickness, new

front 28 mm

rear 24 mm

Minimum brake disc thickness after machining (1)

front 26.6 mm (1)

rear 22.6 mm (1)

(1) The brake disc must only be reworked symmetrically, i.e. from both sides evenly.

Brake disc wear limit

front 26.0 mm

rear 22.0 mm

Thank you!

Also the proper way to measure these is with an inside micrometer that has pointed ends.

Do these measurements include 997.1 "S" ?

Thanks in advance.

Thanks Loren!! BTW, Do you have a recommendation for Replacement Pads? I have had the car out for a few NASA HPDE events. I will try to continue with that once or twice a year. Otherwise it is on the road ~10k a year. Should I go to the trouble of a set for track and a set for street or is there a suitable middle ground. I have had no issues at the track with the stock Porsche pads.

Unless you are running more than 30 minutes at a time I think the OEM pads will be fine. If you are going all out or have runs over 30minutes you can go Pagid - if you go with race pads you will likely want to change back to street pads after events. The squeaking might drive you (and your neighbors crazy otherwise).

Thanks for the info. In NASA they limit time to 15-20 mins per run. I have seen one 30min but not in my classification. I will stick with OEM for now. Mostly street use and I dont want to deal with the squeaking.
