Just FYI, the 3 uses a very different brake system than the 6, assuming my information is correct. In fact, the front disc brakes on the 3 are bigger than those on the 6 (actually, I think the rear 3 brakes are bigger than the front 6 brakes) but I could be very wrong. CSweeney or MZ6ZoomZoom can confirm this easiest as they have Mz6s, but actually, come to the think of it, the specs are pretty available. Before I'd go Brembro, I'd just wait for some good replacement pads to be available, and see if that cleans up the braking performace, since they seem to slow the car well, but also seem to create quite a bit of dust. Somebody suggested ceramic brakes, and I know I would certainly love to have a set, if only to arrest my speeding before a police officer arrests me.
