Performance You Can Feel
The Girodisc system replaces the factory rotors with a precision-engineered, two-piece floating assembly. Each rotor features a CNC-machined 6061-T6 aluminum hat and Girodisc’s proprietary cast-iron friction ring, both manufactured in the USA. Internal curved vanes draw air through the rotor for superior cooling under heavy use, while the floating design allows thermal expansion without distortion. The included spacers and hardware ensure a perfect bolt-on installation that maintains factory geometry and clearance.
