Hi, I had my PCCB rotors measured by the dealer and I got the following:

Front Left: 34.21 mm
Front Right: 34.32 mm
Rear Right: 28.23 mm
Rear Left: 28.24 mm

Car has 95k km (~60k miles) and I believe these are the original rotors.

Any idea how much life I still got in them?

 

Ask the dealer whats the thickness new and what the minimum acceptable tolerance is. Subtract your current thickness by the thickness when new then divide by the amount of miles. This will give you wear per mile. Then subtract the minimum thickness from the remaining thickness, then divide by the wear per miles. This should give you a rough estimate of what you've got left. At 60K they should be original unless someone really worn the first set out with lots of track time.

 

The Porsche maintenance manual lists the following for the 996 turbo w/ PCCB:

Front brake disk thickness new/minimum limit: 34.0mm/33.5mm
Rear brake disk thickness new/minimum limit: 28.0mm/27.5mm

 

Sweet he actually added rotor thickness then!

 

Another 60k and they should be at the brand new thickness.

 

Yeah these measurements worry me. How come they're thicker than new?! Unless I got some Gen II PCCB's that are thicker than Gen I's or something. I don't know.

And today I saw another Turbo S in the shop. Looked at his PCCB's and they were shiny like a mirror. I was SO JEALOUS.
