Detailed Product Features and Specifications

This DFC Brake Rotor - Drilled and Slotted - Black is a vented disc brake rotor with a 348 mm outside diameter and a 62.2 mm overall height, designed to fit BMW X5 and X6 vehicles. 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 type ensures optimal performance when installed correctly.

The rotor has a nominal thickness of 30 mm and a discard thickness of 28.4 mm, indicating when the rotor should be replaced to maintain safe braking performance. The zinc black hat finish provides rust resistance, extending the rotor's service life. It features five bolt holes with a diameter of 16.6 mm and a bolt circle diameter of 120 mm, matching the stud/lug hole pattern of compatible BMW models.
