Audi B5 S4 with Alcon, StopTech BBK Front Rotors
Replace your aging or discontinued Stasis/Alcon rotors with precision-engineered Girodisc two-piece floating front rotors for the Audi B5 S4. These rotors are a complete replacement for the original hat and rotor assembly used in the 355x32mm Alcon or StopTech big brake kits, eliminating the need to chase rare or discontinued components. Designed for enthusiasts who demand top-tier braking control, Girodisc rotors combine advanced materials and race-proven design for consistent, fade-free performance.
Engineered for Performance and Compatibility
The Girodisc system bolts directly to your existing Alcon or StopTech calipers with no modifications required. Built from U.S.-sourced materials, each rotor features 6061-T6 aluminum hats mated to proprietary high-carbon cast iron rings. The result is a lighter, stronger, and more thermally stable rotor designed to handle extreme heat and repeated heavy braking without compromise.
