I have been looking for this one for a while, I just looked at my brakes today to see if upgrading to E0 calipers would be possible (after machining the rotors of course). I notice the cracks then. This is the second time, the first time the rotor were replaced under warrantee. So now I must ask, what causes rotors to crack? I understand that you must first overload the brakes before cracking can even occur, but...
Why do rotors crack?
