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.

Just an FYI, when BMW did my front brakes for the first time the BMW rotors warped within about a month of installation. They replaced for free. Other than the grade of material used I think a mystery on why some rotors will warp when used under normal driving conditions. For me I think proper break-in for the first 500 miles and proper wheel lug torque are critical.

I'll bookmark this post and report back in a month or so and let you know how they are doing.
Neither of your rotors 'warped'. See: brake pad deposition. Break-in the pads correctly and you won't have this problem.
