I have the Disc Italia rotors for the track and they are NOT cyro treated from the factory. Maybe they would crack easier if they weren't treated. I had mind treated because I knew I was going to abuse them something awful. I have no cracking yet.

HDDP has been running the factory rotors with race pads and no problems for a long time since he upgraded to SRT6 brakes, so OEM rotors would be just fine.

I would suggest the Rotex Gold or the ceramic for low dust, BUT others would have to chime in as to their stopping power.

Porterfield does make a R4-S compound pad that is high friction, but lower dust than OEM.

Hope that helps!
