Performance Friction EPIC Rotor Fail :(

I bought a set of performance friction rotors for my E92 in December and have used them at 5 1/2 track events. After 2 weekends they were feeling like they had deposits on them or had warped. I was a bit surprised since I got 7 weekends out of the stock rotors (I know I'm slow as hell). The vibration was manageable and my new rings had not shown up so I went ahead and ran on them.
After 2 run sessions I heard a "twang" kinda noise followed by a sound reminiscent of baseball cards hitting a bicycles spokes.

We pulled in and found this....even freaked out the track mechanics
