BBK suggestion

*snip*

Good post - to add, it appears that majority of the cracks appear on the outer face. I'm assuming this has something to do with the outside having better chance of cooler breeze, uneven pad pressure (from the piston applying pressure on the other side) etc.

I've personally never cracked a rotor (kept a close eye on the rotor thickness, checked for hairline cracks, always had a cool down lap, drove around the pits before parking etc). BUT I've been running street tyres... 2013 will see semis and a BBK upgrade here

What brand is that cracked slotted rotor above?

Not sure sorry.

Funny - after heavy tracking ANY standard rotors will likely weaken and crack ! Some members in this thread gave the impression that its a problem unique to S2K's Pfft.

Haha sorry if I was one of those people, I meant only at the track. Daily it's absolutely fine hence why people were confused that the OP wanted a BBK
