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. Features • Direct bolt-on replacement for OEM 350mm rear rotors• 6061-T6 billet aluminum hats, CNC machined and anodized in the USA• Proprietary cast-iron friction rings for maximum heat resistance• Floating mount system with cadmium-plated steel drive pins• Anti-noise spring washers control rattle and allow thermal expansion• Curved vane design improves cooling airflow and fade resistance• Lightweight construction reduces unsprung and rotational mass• Fully rebuildable – replace friction rings when needed• Sold/priced per pair 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.

Girodisc Mercedes CLK63 Black Series Rear Rotors Upgrade your AMG with Girodisc’s precision-engineered two-piece rear rotors for the Mercedes-Benz CLK63 Black Series. Built as a direct OEM replacement, these lightweight rotors improve cooling, reduce unsprung weight, and deliver consistent, fade-free braking performance for both road and track driving. Vehicle Fitment Mercedes-Benz CLK63 AMG Black Series (C209)Direct OEM replacement – no modifications requiredCompatible with factory calipers and hardware Designed for AMG Precision and Control The Girodisc system replaces the factory one-piece rotors with a two-piece floating design that enhances heat management and braking consistency. The rotor hats are CNC machined from 6061-T6 aircraft-grade aluminum and paired with Girodisc’s proprietary cast-iron friction rings—both made in the USA. This design maintains OEM brake bias and ABS calibration while delivering smoother, more responsive pedal feel and extended rotor life. Features • Direct bolt-on replacement for OEM rear rotors• 6061-T6 billet aluminum hats, machined and anodized in the USA• Proprietary cast-iron friction rings, poured and machined in-house• Floating mount system with cadmium-plated steel drive pins• Anti-noise spring washers eliminate rattle and manage heat expansion• Significantly reduces unsprung and rotational mass• Retains factory brake bias and ABS functionality• Fully rebuildable – replace only the friction rings when needed• Sold/priced per pair Girodisc A2-025 Rear Rotor FAQs: Do these rotors fit directly on the CLK63 Black Series? Yes. They’re designed as a direct bolt-on replacement and work seamlessly with the factory calipers and parking brake assembly. How do they differ from the dimpled and slotted version? This smooth-surface version focuses on maximum pad contact and quieter operation while maintaining the same two-piece floating design and weight reduction benefits. Are these rotors suitable for aggressive driving or track days? Absolutely. Girodisc rotors are engineered for high thermal capacity and stability, making them ideal for both spirited road driving and performance use. Will these reduce brake fade? Yes. The two-piece floating construction and ventilated vane design promote superior cooling and consistent braking under repeated heavy use. Take your CLK63 Black Series braking to the next level with Girodisc rear rotors—crafted for balance, durability, and uncompromising AMG performance.
