Yep, digging up an old thread, but didn't want to start a new one.
I've had the 300V in for approx 3 months, and have only done around 1000k's which included 2 track days. On both track days brakes went pretty early so really didn't push that much. (1st day cracked the rear rotors, second day cracked the fronts :-) ) Should i change?
