Three Wheelin'
IMO This rotor is toast and will start to disintegrate more, the integrity is gone. Ive seen this many times before when CC disc gives up, not with the newest gen yet but happened before.

I initially thought that the rotors could still be used but after researching a bit I've been proven wrong.
Workshop manuals REQUIRE replacement once a rotor has suffered "Edge Damage". See link in the next post.
The comment about drilled holes not being round--that's from brake pad deposits. Heated enough pad materials will start filling the holes and you'll be surprised that they can look very shiny--the same color as the rest of the rotor--to the point that you can tell where the holes end and where the rotor starts.
And others are right--none of us have yet seen a failed Gen3 rotor. And if your dealer's the only one that's taken wheels off in the past they need to make it right for you.

Burning Brakes
Just got back from Champion Motorsports.
Here is the story. Champion Porsche (dealer)had a density tester, they told me to make any appointment for Wednesday, quoted me $350. i then called Champion motorsportst told them to borrow the tester from their parent service department. So, they got the tester when I showed up.
Tester was brand new in the box never used. Mechanic read the directions, and
it was really very simple to use. Three mark numbers on hub, all numbers were below allowable limits.
Basically they are TOAST!
Have 30 k miles on car 25+ track days, i have no clue to how many track miles?
Anybody have experience with Race Brake in Fullerton ,CA??

Well, it took a year, but I think it's safe to say that the Gen 3 rotors are not invincible when punished on the track. 25 days is better than the Gen 2 I used on my spyder. It only took 6 days for the surface to start delaminating on those rotors which probably would have lasted 12 days... on a boxster. I've got 16 days on my iron front AP racing rotors on my GT3 so far and they still look good.

This thread is Halloween scary! 
Thanks for sharing.
I ran done RB iron rotors on an Audi long ago, want a great experience (vibration issues). Could be different now.
Wasn't Porsche going to make iron replacements for PCCB owners available?

How do the fronts get shredded like that, but the rears are ok?

I don't know if RB CCM last longer but the whole set is "only" $13k. And you can refurbish them too.
