There's an article in the SCCA Sports Car magazine this month about brakes. It confirms what I have thought for a long time, that cross-drilled rotors are only good for the disco clubbing bling set, now that the brake pads are better and don't have the gassing problems. When will Porsche learn?

I noticed on the Panamera Porsche is useing slotted rotors...wish they would wake up for the other cars!

All due respect to those who are commenting that those rotors have plenty of life left on them, but I wonder what is the basis for that assertion? I just replaced a set of slotted rotors that looked very similar to Tom's. (different brand fwiw). I looked at them, and couldn't help but worry that the things were going to fail on me in a catastrophic way while on the track. Do we have data from destructive testing that tells us when we need to replace rotors?

Hey Rick, do you have those rotors to fit the 2010 RS with the 380 mm fronts? I loved mine on the 07 RS - got 50 days out of them using RS 29 pads.
I have only 4 days on the OEM '10 rotors and they are holding up better then the '07 rotors, but still like slotted better..

So, from the pictures given I would say there is plenty of time left on the rotors.
AS with all RACE/DE equipment you are using on the race track, it is HIGHLY RECCOMENDED that you very carefully inspect your equipment including rotors EVERYTIME you consider going on track. If you do not know when time is up based on your own inspection, then please get some "PROFESSIONAL" advice as to the condition.
I would offer that current and past users of the DeMan Motorsport GT3 rotors would be the best judge of longevity based on personal experience.
Thanks for all your time..

While I'm not sure if they have 'plenty of life left' (which is relative to the rotor, pad, cooling, and wear rate), I think few would toss them in this condition.
