I had the same discs on the E85 that Roy has. I was very pleased, good braking with EBC pads (UltiMax) no noise and little dust. I'll admit to painting the pads yellow though. Going to paint the hub and edge of the discs like I did on the others with silver paint.I've been looking at these too Tony for the e89, I have fitted Black Diamond 12 grooved discs and Red Stuff pads to both Ms and found them excellent but very noisy, I would be interested to know how these are when you fit them.
Tony.
