The 034Motorsport 375mmx36mm 2-Piece Floating Front Brake Rotor Upgrade Kit for the B9/B9.5 Audi RS5 is a complete replacement brake rotor kit, designed to work flawlessly with the factory front calipers found on the B9/B9.5 Audi RS5.

Weighing in at approximately 27.3lbs, each rotor reduces rotational weight by 0.4lbs on each corner over the factory 27.7lbs 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 rotor is used on both sides of the RS5, 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 Front 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.
