I was using A1RM's as a daily pad. I was informed by QFM national sales manager that they are very harsh on rotors when they are cold. Hence why they chewed through my rotors really quickly as they did the most damage on cold mornings etc (chewed through my new rotors in 20,000km) He advised me to use HPX pads as a street/daily pad but they would fade on the track.
The majority of the time, i was using the pads outside their ideal temp range and hence the premature rotor life. As you would be using the pads at their ideal temperature on the racetrack, you would have less rotor wear.
Luke Youlden was the instructor, very good teacher
