I have a set of the R1 rotors...never have put them on the car though, they're just a back up for me in case I have an issue with my larger RB rotors. Honestly i think the best oem sized rotors you can get are the ebc ultimax rotors. Best price i've found on those is at AutoAnything. The ultimax rotors i've had have gone through a pounding and looked almost as good as the first day I put them on. I've been really pleased with them the most out of all the rotors i've tried on my car.
