Restore your Mercedes’ braking performance with Girodisc D2-170DS 365x26mm dimpled and slotted rear replacement rings. Designed as direct replacements for Girodisc two-piece rotors, these precision-engineered rings combine enhanced cooling with improved pad bite and reduced fade under hard braking.
Vehicle Fitment
Compatible with:
• Mercedes-Benz S63 AMG (W222, W221)
• Mercedes-Benz CL63 AMG (C216)
• Mercedes-Benz SL63 AMG (R231)

Precision Machined for High-Performance Braking
Each Girodisc ring is cast from a proprietary high-carbon iron alloy and machined in-house in the USA. The curved internal vanes act as centrifugal pumps to maximize airflow through the rotor, significantly improving heat dissipation during repeated heavy braking. The dimpled and slotted surface increases pad bite and keeps the braking face cleaner for consistent performance on both road and track.
