Precision Replacement for Maximum Performance
Each Girodisc rotor ring is machined from a proprietary high-carbon iron casting formulated for superior heat tolerance and structural integrity. The curved vane internal design acts as a centrifugal pump, drawing cool air through the disc to reduce operating temperatures and prevent brake fade during extended track sessions. When paired with Girodisc’s floating hat assemblies, these rings provide smooth, quiet operation while maintaining optimal braking balance.
