I have 39,759 miles on my Boxster and my pads look less than half way worn. I measured my left front rotor and got 26.49mm and decided to post to find out what this means for me.

For the Boxster S new rotor thickness is 28mm Front and 24mm Rear. The wear limit is 26mm Front and 22mm Rear. So you've got 2mm from new to wear limit?

Then there is a machining limit which is about 0.6mm thinner than the wear limit for the Non-S Boxster. Does anyone know what it is for the S rotor?

What exactly is the "wear limit" ? It's not the point at which you need your rotor's cut is it? Can't be after only 2mm ?

Is the "machining limit" the point where you have to buy new rotors?

My Bentley's shows the machining limit for the Non-S Boxster rotors at 22mm Front and 18mm Rear. They don't provide this data for the S model.

Am I only 0.49mm from having to turn my rotors? How long will that 0.49 last me?
