2-Piece Floating Front Brake Rotor Upgrade Kit

The 034Motorsport 374mmx36mm 2-piece Floating Front Brake Rotor Upgrade Kit for the 8Y Audi RS3 is a complete replacement brake rotor kit, designed to work flawlessly with the factory front calipers found on the 8Y Audi RS3.

Weighing in at approximately 28.0 lbs, the lightweight design retains proper thermal mass in the rings and improves metallurgy to adequately capture heat, while utilizing 72 enhanced directionally curved vanes to flow cool air through the rotor to dissipate heat forcefully.

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 RS3, 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 rotor utilizes J-Slot slots which increase braking surface area over drilled rotors as well as clean the pad and surface of contaminants and allow hot pad outgassing, all while reducing overall braking noise compared to a traditional slotted rotor. This J-Slot design also improves upon the OEM drilled rotors, as drilled rotors are prone to cracking after repeated abuse.

With its true 2-piece design, 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. This 2-piece design also makes repair costs in the future significantly less over time, as only the rotor rings would need to be replaced.

034Motorsport 2-Piece Rotors have been thoroughly tested in high-intensity motorsport events, proven to significantly improve braking and thermal headroom and for extreme performance street and track driving, making them the perfect replacement rotor for your 8Y Audi RS3.
