Detailed Product Features and Specifications

This Dynamite Friction DFC Brake Rotor - Drilled and Slotted - Black is a vented disc brake rotor with a 321 mm outside diameter and a 45.5 mm overall height. The rotor surface is both drilled and slotted, which helps to evacuate gases, dust, and water from the braking surface, improving brake pad contact and reducing fade. The directional design ensures optimal performance when installed correctly. The rotor’s hat is finished with a zinc black coating to resist rust and corrosion, extending the rotor’s service life. It features five bolt holes with a diameter of 14.3 mm and a bolt circle diameter of 115 mm, matching the stud/lug hole pattern for secure mounting. The nominal thickness is 30 mm, with a discard thickness of 27 mm, indicating when the rotor should be replaced to maintain safe braking performance.

About the DFC Brake Rotor - Drilled and Slotted - Black Product Line
