The curved vane internal structure acts as a centrifugal air pump, pulling cooling air through the rotor to maintain ideal temperatures under repeated hard braking. Sold in pairs and supplied with new hardware, these rings bolt directly to your existing Girodisc aluminum hats with no modification required.
