I replaced the Zimmerman rotors with Textar rotors and kept my Bosch pads ( sand them a bit). So far the vibration is gone but I am doing a gentle break-in this time so I will report back after 500-600 miles.

I started suspecting the rotors when I realized that the vibration was proportional to the heat introduced into the brakes, so when the brakes were warm, the vibration was bad.

Bad set of rotors? Bad thrust arm and wheel bearing that somehow damaged rotors... Don't know, I will return that set of Zimmerman to my supplier for sure and hope that this is the last of the vibrations.

I'll keep my fingers crossed for you. Like I said, we went through a rash of this with E39s that we put Zimmermans on. We switched brands and the problems went away immediately.
