Has anyone had any luck in BMW covering the repair?
Relax! Unless you have done something really stupid (like engaging the parking brake after a race lap), you don't have warped rotors. What you probably experience now is a rattle when braking at speeds >50mph, right? This comes from pad deposits on the disks. I had the same after a weekend on the Nurburgring.
This can be fixed at almost no cost: Go to your dealer let them sand/polish your discs. Then after a couple hundred miles of driving braking will be as smooth as before.
