034Motorsport 2-Piece Floating Front Brake Rotor Upgrade Kit for Audi 4M/4M.5 SQ7/SQ8

This 2-piece floating front rotor kit upgrades the front brakes on the Audi 4M and 4M.5 SQ7 and the SQ8, and it is designed to work with the factory front calipers. Each 400mm x 38mm rotor pairs a 6061-T6 aluminium hat with a proprietary alloy disc, and 034Motorsport quotes about 32.5lbs per rotor against 35.3lbs for the factory part. The disc has 72 directionally curved vanes oriented separately for each side, which the brand says corrects the factory use of one rotor on both sides, plus J-slots that clean the pad and surface and let hot pad gases escape. High strength alloy steel bobbins carry the braking load and allow axial and radial float, so the hat and disc can expand and contract safely with heat.
