Detailed Product Features and Specifications

This DFC Brake Rotor - Drilled and Slotted - Silver is constructed as a solid rotor with a nominal thickness of 12 mm and a discard thickness of 10 mm, ensuring durability and safety margins for wear. The rotor's surface is both drilled and slotted, which helps to reduce brake fade by improving heat dissipation and allowing gases and debris to escape during braking. The rotor's hat is finished with a zinc silver coating that provides rust resistance, extending the rotor's service life.

With an outside diameter of 302 mm and an overall height of 49.5 mm, this rotor fits precisely on Audi A6 and A6 Quattro models requiring a 5-bolt pattern with a 112.2 mm bolt circle diameter. The center hole diameter measures 68 mm, and the stud/lug hole diameter is 15.3 mm, matching factory specifications for proper fitment.
