034Motorsport 2 Piece Floating Rear Brake Rotor Upgrade Kit - B9/B9.5 S4/S5/SQ5

Sale price£1,132.72 GBP


The 034Motorsport 330mmx22mm 2-Piece Floating Rear Brake Rotor Upgrade Kit for the B9 & B9.5 Audi S4/S5/SQ5 is a complete replacement brake rotor kit, designed to work flawlessly with the factory rear calipers found on the B9 & B9.5 S4/S5/SQ5.


Weighing in at approximately 12.15lbs, each rotor reduces rotational weight by 4.50lbs per corner over the factory 16.65lb 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. From the factory, the same straight-veined rotor is used on both sides of the S4. The 034Motorsport rotors utilize 72 directionally curved vanes to forcefully flow cool air through the rotor to dissipate heat and are unique to the left and right axle to provide a substantial increase in cooling efficiency over the factory rotor design.


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.


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