I've got brembo supersports (drilled and grooved) on the front and standard discs on the rear.
Works really well, even on track.
But you have to brake them in a bit.
With my first trackday (with brand new discs) they where smoking when i entered the pitlane after 10-15 laps.
Brembo are OEM equipment on a number of sporty vehicles including Porsche, i fitted Brembo discs to mine recently, to be honest at this level they will all be made from cast iron, so not a lot to choose from any of the makes, but you can get a good deal on the Brembo i paid £52 for vented fronts (3.0) the 1.9 solid fronts are about £38. The money in my opinion should be spent on the pads.
