Under what conditions do you experience this vibration? Only in the wet? Only when braking from high speeds? Only if you really romp on the brakes hard, or even if you squeeze them on gradually?

Need some more details about how this is triggered in order to attempt to diagnose.

It happens when I hit the brakes hard from higher speeds. Other times there's no sign of it.

i second this. i was told mine were warped by the dealer and that they wouldnt replace them under warranty. i didnt believe it and thought that it was pad deposits so ran my race pads for a little bit and wow fixed. i tried to get a tech inspection for BMWCCA while my rotors were "warped" and they didnt want to pass me saying they were the worst warped rotors they have seen.
