• Overall diameter of 294 mm and height of 75 mm

Detailed Product Features and Specifications

This DFC Brake Rotor - Drilled and Slotted - Black is constructed with a vented rotor design that helps maintain optimal operating temperatures by allowing air to flow between the rotor surfaces. The rotor’s surface is both drilled and slotted, which assists in channeling away brake dust, gases, and water, improving braking consistency and reducing fade. The directional brake surface is engineered to optimize performance when installed in the correct orientation.

The rotor’s hat is finished with a zinc black coating, providing rust resistance and extending the rotor’s service life. With a nominal thickness of 19 mm and a discard thickness of 17.4 mm, this rotor meets precise wear limits to ensure safe operation. The 5-lug bolt pattern with 14.2 mm diameter holes and a 120 mm bolt circle diameter matches the BMW Z4 specifications for a secure fit.
