ATE power disc pulsation when braking

[Ivan Demkovitch]

I think that will be a lesson for us...
I went with ATE Powerdiscs on my BMW and have those pulsations after 10k.. I 
assume it will get worse. And I'm not at the end of grooves yet...

On that car I will be back with stock rotors/pads. Can't get any better.
