Precision-Engineered for the MQB Platform
Each Girodisc D2-171 ring is cast and machined in the USA using Girodisc’s proprietary high-carbon iron alloy for strength, heat capacity, and consistent friction properties. The curved vane internal structure acts as a centrifugal air pump, drawing cooling air through the rotor to minimize fade and maintain braking stability. Sold as a pair, the kit includes new hardware and installs directly to your existing Girodisc aluminum hats for a perfect fit.
