034Motorsport 2-Piece Floating Front Brake Rotor Upgrade Kit for Audi B8/B8.5 S4/S5/Q5

This kit replaces the front brake rotors on the B8 and B8.5 Audi S4 and S5, and the Q5, with 345x30mm 2-piece floating rotors designed to work with the factory front calipers. 034Motorsport says each rotor weighs about 19.00lbs, which is 5.10lbs less than the 24.10lb 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 72 directionally curved vanes that are unique to the left and right sides, where the factory uses the same straight-veined rotor on both. A J-Slot face cleans the pad surface and allows pad outgassing, and floating alloy steel bobbins let the hat and disc expand safely with heat.
