Precision-Engineered for AMG Performance
The Girodisc system directly replaces the OEM cast rotors with a two-piece floating assembly for improved response and durability. Each rotor features a CNC-machined 6061-T6 aluminum hat mated to Girodisc’s proprietary cast-iron friction ring, both made in the USA. Internal curved vanes act as a centrifugal pump, forcing air through the rotor to manage heat under repeated heavy braking. This design maintains factory brake bias and ABS calibration while providing quicker recovery and more consistent pedal feel.
