its currently running DS2500s with aftermarket drilled/grooved discs

i have some issues with the brakes constantly squeaky, sounds/feels like metal on metal grinding when braking from high speeds.

and after just 2 laps of donno i was getting so much judder thru the steering wheel it was unreal! (heat related, they were fine after a cool)



sum1 on the BMW forums just said that he knows a LOT of peopl ehaving identical heat/judder issues to me with DS2500s and swapping pads cured it.
