My personal experience was surprising especially since I was running PFC pads with them. I bed the pads in on the new rotors and went to the track. They heat cracked after the first use and then they grew really quickly. I only got 4 days out of them and some of the cracks were getting alarmingly wide. Compared to the E46 OEM M3 euro rotors where I got 6 weekends out of. I kept going and eeked out 2 more weekends but I had back up rotors with me.
See the thread below. I don't think my rotors were far from looking like that. Now that's 2 of 4 people that I know run these rotors. Maybe bad luck but I'll personally pass on these.

Compared to my stoptech rotors with my stoptech kit (about the same size) which I got 16 months of constant track days and street driving out of (and the rings are cheaper).
