The 034Motorsport 2-Piece Floating Rear Brake Rotor Upgrade Kit for the Audi C8 S6/S7, D5 A8/S8, & 4M/4M.5 Q7/SQ7/Q8/SQ8 is a complete replacement 350mmx28mm brake rotor kit, designed to work flawlessly with the factory rear calipers found on the Audi C8 S6/S7, D5 A8/S8, & 4M/4M.5 Q7/SQ7/Q8/SQ8

Weighing in at approximately 17.1lbs, each rotor reduces rotational weight by 3.3lbs on each corner over the factory 20.4lb rotors. While reducing weight, the rotor retains proper thermal mass in the rings to adequately capture, and dissipate heat

The central hat portion of the 034Motorsport rotor is made of 6061-T6 aircraft specification aluminum. The disc is constructed out of a proprietary metal alloy that can withstand immense braking temperatures while holding form allowing hard street use and long days at the track allowing you to drive versus working on the car. From the factory, the same rotor is used on both sides of the C8 S6/S7, D5 A8/S8, & 4M/4M.5 Q7/SQ7/Q8/SQ8, leading to one side having incorrect venting and cooling effects. The 034Motorsport 2-Piece Floating Front Brake Rotor Upgrade Kit utilizes 72 directionally curved vanes properly oriented for each side of the vehicle to forcefully flow cool air through both rotors to dissipate heat equally.

The face of the 034Motorsport 2-Piece Floating Rear Brake Rotor Upgrade Kit utilizes J-Slot slots to clean the pad and surface of contaminants and allows hot pad outgassing, all while reducing overall braking noise compared to a traditional slotted rotor.

The 034Motorsport rotor and hat floating mount system utilizes high strength alloy steel bobbins. The pins take the load from braking actions while maintaining the axial and radial float between the hat and disc, allowing for safe expansion and contraction from heat.
