May of cured it temporaily, Spoke to Kerry Perkins from DBA I said I was running HPX pads and he asked whether they had a chamfered edge, As we all know they dont, he asked me to remove the pads and file a chamfer on the leading and trailing edge of the pad, I just finished doing the front took the car for a drive and the roughness and vibration is almost gone. So I dont think I will be using a non chamfered pad on slotted rotors agin. Not sure if mine is an isolated problem. I will give it a week and update this tread again. See if the vibration returns. If it does not reurn I will do the rears.
