A forum search turned up some specs for the PFL front rotors which said:
New 36mm; service limit 34mm; wear limit 33.4mm

Are front thickness specs the same for FL cars?

What are specs for the rear rotors?

As far as I know the rears are 26 mm. You can also let them wear about 2 mm down to 24 before they need to be replaced.

The min spec is stamped on the rotor hub or some AMG model's it's on the outer lip edge of the rotor.

Thanks Rocman8 - jacking up the car and pulling the wheels should answer my question. I'm just hoping that someone can save me the work. . . .

That's good news. I've worn completely through a set of RB track pads and halfway through of a set of OEM pads. Dealer just did my final service before warranty runs out next week. They measured rotors at 35 front and 25 rear, so I should be in good shape. Thanks!

No need to remove the wheels to read the specs. Just need a flashlight.

Any ideas on how to measure the rear rotor without removing it? The brake shield doesn't have an opening that I can find for my micrometer. I have a flimsy digital caliper, put I don't see space for that and some quarters to get a disc measurement instead of an edge measurement.
