Girodisc McLaren 350mm Rear Rotors
Enhance your McLaren’s braking precision with Girodisc 350mm two-piece rear rotors. Built as a direct OEM replacement for cars originally equipped with cast iron rotors, these lightweight, high-performance assemblies improve cooling, reduce unsprung weight, and deliver superior pedal feel without altering factory brake balance or ABS function.
Vehicle Fitment
Compatible with McLaren models originally equipped with 350mm cast iron rear rotors
Direct OEM replacement – no modifications required
Retains factory brake bias and electronic controls
Lightweight Performance, Track-Proven Strength
The Girodisc system replaces the factory one-piece rotors with a fully floating two-piece assembly engineered for superior heat management and durability. The rotor hats are machined from 6061-T6 aircraft-grade aluminum, while the friction rings are cast from Girodisc’s proprietary iron alloy—poured, machined, and balanced in-house in the USA. The curved vane internal structure acts as a centrifugal pump, efficiently channeling air to cool the braking surfaces during aggressive driving or track sessions.

Girodisc A2-023 Rear Rotor FAQs:
Will these rotors fit McLaren models equipped with carbon ceramics? No. The A2-023 kit is designed for vehicles originally equipped with cast iron rotors. Carbon ceramic conversions require a different Girodisc setup.
How do these rotors improve performance? The two-piece design lowers unsprung weight, improves heat dissipation, and maintains consistent braking under heavy use, all while retaining OEM brake bias and control.
Do the curved vanes make a difference? Yes. The vane system acts as a centrifugal air pump, significantly improving airflow and cooling efficiency for reduced fade during extended high-temperature braking.
Are they noisy or prone to rattle? No. Girodisc’s anti-noise spring washer system prevents rattle while allowing the rotor to expand freely under heat, ensuring smooth and quiet operation.
Take your McLaren’s braking to the next level with Girodisc 350mm rear rotors—precision-engineered for lighter weight, superior cooling, and track-proven reliability.
