034Motorsport 2-Piece Floating Rear Brake Rotor Upgrade Kit for Audi B9/B9.5 S4/S5/SQ5

This kit fits 330x22mm 2-piece floating rear brake rotors to the B9 and B9.5 Audi S4, S5 and SQ5, designed to work with the factory rear calipers. 034Motorsport says each rotor weighs about 12.15lbs, which is 4.50lbs less than the 16.65lb factory rotor, while keeping enough thermal mass in the rings to absorb and shed heat. The hat is 6061-T6 aluminium with Type III hard anodising, and the disc has a J-Slot face that cleans the pad surface and allows pad outgassing. Floating alloy steel bobbins join the hat and disc so they can expand and contract safely with heat.
