McLaren 620R Rear Rotors

The Girodisc system is a direct replacement for the OE rear rotors on the McLaren 620R. Designed for uncompromising track and street performance, these lightweight 2-piece floating rotors bolt directly to the car without any modifications. They maintain factory brake bias and ABS calibration while significantly improving heat dissipation, reducing unsprung mass, and enhancing overall braking consistency.
Precision-Engineered for the Ultimate Track Weapon
Built to handle the extreme braking loads of high-performance McLaren applications, Girodisc rotors are fully machined and assembled in the USA using aerospace-grade materials. The rotor hats are CNC-cut from 6061-T6 aluminum and anodized for durability, while the rings are cast from Girodisc’s proprietary high-carbon iron alloy. This advanced metallurgy ensures strength, thermal stability, and smooth pedal modulation even after repeated heat cycles.
