What kind of pads are they selling you over the pond that would clog your holes? (That kind of sounds obscene.) I've never have had that problem with any of the cross drilled discs on any of my vehicles. I will have to agree with Ajmevans, OldMots, and Plums, most of the engineering has been proven on the race track. Also if your not aggressively braking, the performance brakes will have a tendency to glaze, which will make them squeal. Aggressive braking will keep the glaze off.

Hi folks, thought I'd relay my own experiences of brake noise.... but for the record I use normal, not drilled or grooved, EBC front discs on my XK8, with no braking issues or perceived lack of brake performance whatsoever.
My last car, a Chrysler 300c hemi, needed new front discs so I went for EBC drilled and grooved with redstuff pads, and had horrible rotor noise when braking. I cured this noise by swapping the discs side to side, so that the normal direction of rotation now had the slots drawing air in, not centrifuging it out. The noise was the grooves trying to push the pads out from their seating against the caliper carrier brackets, against the moving part of the caliper, causing them to resonate. With the discs swapped, all was quiet, as the grooves were now trying to pull the pads in against the carrier brackets, avoiding any movement or resonance. Hope this helps....?
