Girodisc Mercedes S63/65, CL63/65 Rear Rotors
Enhance your AMG’s braking performance with Girodisc’s precision-engineered two-piece rear rotors for Mercedes S63/65 and CL63/65 models. These rotors are a direct OEM replacement, delivering improved cooling efficiency, reduced unsprung weight, and exceptional pedal feel for both spirited street driving and heavy braking on track.
Precision Engineering for Flagship AMG Models
The Girodisc system bolts directly to factory hubs and calipers—no modifications required. Each rotor features a U.S.-sourced 6061-T6 aluminum hat paired with Girodisc’s proprietary high-carbon cast iron friction ring. The floating two-piece design allows the rotors to expand evenly under heat, maintaining consistent pad contact and preventing warping during repeated high-speed stops. Curved internal vanes draw cooling air through the disc to keep temperatures stable under extreme braking loads.

Girodisc A2-170 Rear Rotor FAQs:
Do these rotors work with the AMG’s factory carbon-ceramic option? No. These are designed for models equipped with the standard iron rotor package. Vehicles with carbon-ceramic brakes require a dedicated conversion kit.
How much weight reduction do these rotors provide? Girodisc rotors typically save 3–4 lbs per corner over OEM one-piece units, improving suspension compliance and acceleration response.
Will installing these affect the car’s electronic stability or brake distribution systems? Not at all. The Girodisc rotors retain OEM geometry and ABS tone-ring compatibility for seamless integration with all factory electronics.
Are these suitable for the heavy S-Class chassis on track? Yes. The floating two-piece construction and directional vanes manage heat exceptionally well, preventing fade and ensuring consistent braking performance even during repeated high-speed stops.
Give your AMG the braking refinement it deserves with Girodisc’s rear rotors—engineered to balance luxury comfort with race-ready stopping power.
