Detailed Product Description

The DFC Geoperformance Rotor - Drilled and Slotted from Dynamite Friction is designed to meet the braking demands of various Audi models such as the A4, A5, A6, and Q5 series. Its vented construction allows for efficient heat dissipation during braking, reducing the risk of brake fade under heavy use. The rotor’s directional surface features both drilled holes and slots, which help to evacuate gases, dust, and water from the braking surface, maintaining consistent pad contact and improving overall braking response.

With a nominal thickness of 30 mm and a discard thickness of 28 mm, this rotor ensures a long service life while maintaining safety standards. The rust resistant coating and Geospec silver grey hat finish provide corrosion protection and a clean appearance, suitable for vehicles exposed to various weather conditions. The 5-bolt hole pattern with a 112 mm bolt circle diameter matches the factory specifications for compatible Audi models, ensuring proper fitment and installation.
