Lightweight Performance Upgrade
The Girodisc system bolts directly to the car—no modifications required. Each two-piece rotor features a CNC-machined 6061-T6 aluminum hat paired with Girodisc’s proprietary high-carbon cast-iron friction ring. The result is a lightweight, high-strength assembly that cuts unsprung mass for sharper handling and faster response. Internal curved vanes act as centrifugal pumps, forcing air through the disc to dissipate heat efficiently under repeated high-load braking.
