The 034Motorsport 370mmx34mm 2-Piece Floating Front Brake Rotor Upgrade Kit for the 8S Audi TTRS is a complete replacement brake rotor kit, designed to work flawlessly with the factory front calipers found on the 8S Audi TTRS.

Weighing in at approximately 21.9lbs, each rotor reduces rotational weight by 5.4lbs on each corner over the factory 27.3lb 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. The rotor 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.

The rotor and hat have a floating mount system that 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.
