Girodisc Mercedes S55 / CL55 Rear Rotors (Dimpled & Slotted)
The Girodisc A2-072DS Rear Rotor Kit delivers a lightweight, high-performance braking upgrade for Mercedes-Benz S55 and CL55 models. These 2-piece, fully floating rotors feature a dimpled and slotted surface for superior pad bite and efficient heat evacuation. Designed as a direct OE replacement, the kit bolts on without any modifications while maintaining factory brake bias and ABS performance.
Lightweight 2-Piece Construction
Each Girodisc assembly combines a precision-machined 6061-T6 aluminum hat with a proprietary cast iron rotor ring, engineered for strength, cooling, and weight reduction. The 2-piece design significantly decreases unsprung and rotational mass, improving acceleration, suspension response, and overall handling. The dimpled and slotted rotor faces provide consistent pad deglazing and gas venting for enhanced braking feel under repeated heavy use.
Floating Mount System & Anti-Noise Hardware
Girodisc’s advanced floating mount system uses 10 high-strength alloy steel drive pins manufactured in-house in the USA. These pins are cadmium-plated for corrosion resistance and secured by class 12.9 cap screws with hardened washers. Anti-noise spring washers allow the rotor to expand and contract with heat while eliminating unwanted rattle, ensuring quiet operation for street driving and track sessions alike.
