Favorite is to wave cut the outer perimeter like on the RS Audis which reduces weight a bit and exposes more surface area at the hottest part of the rotor (which does add cooling value). I've never run them a full 30hrs, but have lots of sets of pads at about 40% left - kind of false economy to have to pit in a 24hr enduro to save on pads... So I use them for 15 - 24hrs (depending on race length), and the rotors last a long time (I've got ducts to the center of the rotors too).

I also run cooling ducts to the center of the rotors on my rally car. Still wouldn't get near that longevity. Must be too much left foot braking overlap while on throttle !!
