This is normal for track use, and BMW will do nothing for you in that event. However, if you haven't used the car on a track then it's not normal, not even with age, as it's a sign of extreme heat, and they may help you out with it. But I'm sure it's track use.

Yep, you can definitely see this is a result of track use as you can see the pad deposit in the holes of the rotors.
It seems this car is driven on a fast/high speed track with traction control on. If your rear brakes are discolouring over the front brakes, then it means the rears are clamping down with traction control intervention when the car is at high speed, which causes a lot of heat. (If you drive with traction control fully off, this will negate the rear brakes clamping down without your braking input as traction control won't intervene). Think of it this way, if you are travelling at 180 km p/h and you see your traction control light flickering, it means the rear brakes have slightly clamped onto the rotor, you can then imagine the amount of heat that would generate.

Interesting to know. Seems like MDM was doing small brake intervention to introduce high speed stability. I always run with Mdm at my local track day but we don't have a lot of high speed corners to signify what you experienced.
