Detailed Product Features and Specifications

This DFC Brake Rotor - Drilled and Slotted - Silver 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 in various conditions. The directional surface type ensures optimal performance when installed correctly according to the rotation direction.

The rotor’s nominal thickness is 30 mm, with a discard thickness of 28.5 mm, indicating when replacement is necessary to maintain safe braking. The rotor features a plain disc finish combined with a zinc silver rust-resistant coating on the hat area, enhancing corrosion resistance and extending service life. The 5-bolt hole pattern with a 16.24 mm diameter and 126.8 mm bolt circle diameter matches the factory specifications for Jeep Commander and Grand Cherokee models, ensuring proper fitment.
