Rotors, Rr, 330x22, B9 RS5

The 034Motorsport 2-Piece Floating Rear Brake Rotor Upgrade Kit is a complete replacement 330mmx22mm brake rotor kit designed to work flawlessly with the factory rear calipers found on the B9/B9.5 Audi RS4/RS5. Each rotor weighs approximately 12.1lbs, reducing rotational weight by 1.7lbs per corner compared to the factory 13.8lb rotors. While reducing weight, the rotor retains proper thermal mass in the rings to adequately capture and dissipate heat. The central hat portion is made of 6061-T6 aircraft specification aluminum. The disc is constructed from a proprietary metal alloy that can withstand immense braking temperatures while holding form. It utilizes 72 directionally curved vanes to forcefully flow cool air through the rotor to dissipate heat. The face of the rotor 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.
