Don't have enough miles or track days (1) yet to determine rotor life. So far with brand new DBA 5000 front no edge has developed after 215 track and 1200 road miles. I must say with the Hawks rotor wear was minimal as well. I use the brakes moderately hard on track, don't think I go anywhere as deep as you, yellow boss or Gary on track so I don't reall eat up pads, rotors or tires.
