• Overall diameter of 305 mm and height of 55.6 mm

Detailed Product Features and Specifications

This DFC Brake Rotor - Drilled and Slotted - Black is constructed with a vented rotor design that helps dissipate heat more effectively than solid rotors, reducing the risk of brake fade during extended use. The rotor surface is both drilled and slotted, which assists in channeling away brake dust, gases, and water, improving braking consistency and pad bite. The directional brake surface ensures optimal 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 20 mm and a discard thickness of 18.4 mm, this rotor meets precise wear limits for safe operation. The 305 mm outside diameter and 55.6 mm height are designed to match the Chevrolet Corvette’s brake system specifications. The five 13 mm bolt holes arranged on a 120.7 mm bolt circle diameter ensure proper fitment and secure mounting.
