Detailed Product Features and Specifications

This DFC Brake Rotor - Drilled and Slotted - Silver from Dynamite Friction is designed with a vented rotor type 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 aids in channeling away brake dust, gases, and water, improving braking consistency in various conditions. The directional brake surface ensures optimal performance when installed correctly according to rotation direction.

The rotor's nominal thickness is 18 mm, with a discard thickness of 16 mm, indicating when replacement is necessary to maintain safe braking. The rotor features a plain disc finish and a zinc silver hat finish that includes a rust-resistant coating to protect against corrosion and extend service life. With 5 bolt holes and a bolt circle diameter of 114.3 mm, this rotor fits securely on the Mazda CX-9 hub assembly.
