I can't say for a fact because I never had one but I'd say for the people saying that they eat up pads faster, that's probably because it's got better braking. A rotor that has more bite, it would make since for it to wear pads faster. Either that or maybe they didn't have good pads put on and they wore faster. Just my thoughts.also the wave brake discs, any reason to have them over OEM? been looking at them and I keep seeing different opinions. Some people say they eat the pads really fast, others say they have improved braking. What gives?
