Detailed Product Features and Specifications

This DFC Geoperformance Rotor features a vented design that helps reduce brake fade by allowing air to flow through the rotor during braking. The drilled and slotted surface improves water and debris evacuation, which is critical for maintaining consistent braking performance in various driving conditions. The rotor’s nominal thickness is 22 mm, with a discard thickness of 20 mm, ensuring a reliable service life before replacement is necessary. The rust resistant coating and Geospec silver grey hat finish provide corrosion protection and a clean appearance over time.

With 5 bolt holes and a bolt circle diameter of 112 mm, this rotor is engineered to fit securely on compatible Audi and Volkswagen vehicles. The directional surface design enhances braking efficiency by channeling gases and heat away from the pad contact area.
