Somebody on this forum (Maybe
@Cuda340 ?) posted a good cross section of a Brembo pad, explaining the design choices. I can't seem to find it now.
Anyway, Brake Dust is a normal characteristic of many performance cars. I agree with 19johned53, the factory Brembo pads are the best pads for our cars. If you can live with some dust, they do everything else very well. For street/spirited driving in a heavy car, in all temperature ranges, even occasional track use, I would go with factory 4 piston Brembo pads and rotors. They have the best match up of compromises. They even seem to last a long time. It doesn't surprise me that Brembo doesn't offer a different pad for our cars. I don't see how they could get it much better.
