Lightweight, High-Performance Construction
The Girodisc system is a direct OEM replacement that bolts to the factory hubs with no modifications required. Each rotor features a 6061-T6 billet aluminum hat mated to Girodisc’s proprietary cast-iron friction ring for optimal durability and thermal efficiency. The floating design allows for controlled heat expansion, eliminating warping and maintaining consistent pedal feel. Internal curved vanes act as centrifugal pumps, drawing cooling air through the disc to keep braking temperatures stable under aggressive use.
