034Motorsport 350mm 2-Piece and Floating Rear Disc Upgrade - MQB
034Motorsport’s 350mm 2-Piece Floating Rear Brake Rotor Upgrade for MQB Audi and Volkswagen models delivers a significant increase in braking performance while reducing weight and improving heat management. This complete kit includes lightweight 350mm floating rotors and caliper carrier conversion brackets, engineered to work perfectly with the factory rear calipers. Each rotor weighs roughly 14 lbs—1 lb lighter per corner than the stock 310mm rotors—while offering a substantial diameter increase to boost stopping power. The aerospace-grade 6061-T6 aluminum hat is paired with a high-temperature CM-250 alloy rotor ring featuring 72 curved vanes that push cooling air through the disc for exceptional heat dissipation. J-hook slots on the friction surface help clean the brake pads, reduce glazing, and manage outgassing under repeated hard braking. A floating bobbin system allows the rotor to expand and contract safely under extreme heat, improving durability and reducing long-term maintenance costs. Ideal for street, track, and HPDE driving, this upgrade keeps braking performance consistent, cool, and reliable all day long.
