Ah, I found this:
Alcon Advantage Extreme Brake Kit Front Mono4 BMW E90/92 3-Series incl M3 08-11
Any weight specs you can provide would be appreciated.
Also, on my A4, I got Alcon rotors for the rear. They're solid (no veins) one-piece rotors, but they have the "C" indentations in the surface. Do you know if anything like that is available for the E92 M3?
