Detailed Product Features and Specifications

This DFC Brake Rotor - Drilled and Slotted - Silver is a solid rotor designed to provide consistent braking for Audi A6 Quattro and Allroad Quattro vehicles. The rotor measures 255 mm in outside diameter with an overall height of 47.8 mm. It features a nominal thickness of 10 mm and a discard thickness of 8 mm, ensuring clear service limits for safe operation.

The rotor 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 directional surface design further enhances braking efficiency by optimizing pad contact and water dispersion.

The rotor hat is finished with a zinc silver coating that provides rust resistance, extending the rotor’s service life. It includes five bolt holes with a 112 mm bolt circle diameter and a center hole diameter of 68 mm, matching the factory specifications for the intended Audi models.
