I'm thinking about picking up
APR's new rotors for my R32 brakes -- they aren't terribly more expensive than my original plan of StopTech rotors. I did a little bit of research and it seems that APR is basically rebadging some rotors from a company called
Powerbrake out of South Africa. They're big in the off-roading/overlanding/rally world and seems like owners only have good things to say about Powerbrake's hardware.
If you compare the two pages I linked, you'll see the stark similarities in description.
