Vehicle Fitment
Mercedes-Benz S55 AMG (W220)

Lightweight, High-Performance Design
The Girodisc system installs directly on your factory hubs with no modifications required. Each rotor combines a CNC-machined 6061-T6 aluminum hat with Girodisc’s proprietary cast-iron friction ring, both manufactured and machined in the USA. The floating mount system allows for independent thermal expansion, reducing distortion and maintaining even pad contact under extreme braking. Internal curved vanes act as centrifugal pumps, drawing air through the disc for optimal heat dissipation and consistent performance lap after lap.
