Performance and Precision
This complete rotor assembly replaces both the hat and rotor, eliminating the need for rare Stasis replacements. Each unit features a CNC-machined 6061-T6 aluminum hat and Girodisc’s proprietary cast-iron friction ring. The curved vane design acts as a centrifugal pump, drawing air through the rotor for exceptional cooling under track or spirited use. A floating mount system allows the disc to expand evenly under heat, preserving pad contact and preventing warping.
