Similar to NEUSPEED 370mm Front Rotor, this 350mm Rear Rotor also features 2pc Full-Floating construction with CNC 7075-T6 billet aluminum hat. The entire rotor is designed specifically for the new VW/AUDI MQB platform. It has the correct rotor offset, bolt pitch diameter, as well as hub holding screw, unlike others that use Mercedes SUV steel rotor with different offset, much heavier weight, and require spacer or hub ring to get the rotor concentric to the wheel bearing.
The increased rotor diameter from 310mm to 350mm provides more friction surface and material for better heat dissipation. It also increases brake torque leverage improving rear braking without the need to mess around with brake bias.
