IMHO... they are cheap crap rotors. I went through two sets on my front axle, always warped within 1500 miles. I even resurfaced once so they warped three times on me. Finally took car to dealer who said the rotors were poor quality and replaced with OEM... no more warping since. If I was gonna try them again on an e60 I would suggest the slotted version to help with heat build up. I should add that I have used these rotors more successfully on other model BMWs and I do believe the e60/e61 brake design is undersized.
