Girodisc GD355.32.62 355x32mm Replacement Rotor Rings (Wide Annulus)
The Girodisc GD355.32.62 Replacement Rotor Rings (Wide Annulus) are precision-engineered to replace worn iron rings on Girodisc two-piece brake systems using the D62 hat configuration. These 355x32mm rings are crafted for performance vehicles utilizing Brembo big brake kits that require a wide annulus pad contact area.
Restore Performance with Genuine Girodisc Components
Manufactured in the USA from Girodisc’s proprietary cast iron alloy, these rings are engineered for maximum strength, heat resistance, and consistent friction. The wide annulus design provides a larger pad contact area for improved wear balance and braking stability. Each rotor features directional curved vanes that act as a centrifugal pump, pulling cool air through the disc to minimize fade and maintain optimal performance under track conditions.
