Girodisc D2-100 Audi RS4 Rear Replacement Ring FAQs
Do these rings work with the factory Audi RS4 brake pads? Yes, the Girodisc D2-100 rings are fully compatible with factory RS4 pad compounds as well as popular track options from Pagid, Ferodo, and Hawk.
How should I bed the new Girodisc rings after installation? Perform 8–10 moderate stops from 60 mph to 10 mph, allowing the brakes to cool between runs. This evenly transfers pad material and prevents uneven deposits.
Are these rings suitable for track use? Absolutely. The high-carbon alloy and floating design provide consistent performance under repeated high-temperature braking.
Can these rotors be resurfaced or turned? No. Due to the directional vane design and strict tolerances, resurfacing is not recommended — replacement rings are the correct service method.
