• Overall diameter of 340 mm and height of 125 mm

Detailed Product Features and Specifications

This Dynamite Friction rotor is constructed with a vented design that allows air to flow between the rotor surfaces, helping to dissipate heat more effectively during braking. The rotor’s surface is both drilled and slotted, which aids in removing brake dust, gases, and water from the contact area, improving brake pad bite and reducing the risk of brake fade. The directional surface pattern is optimized for the rotational direction of the rotor, ensuring consistent performance.

The rotor’s hat is finished in zinc silver, providing corrosion resistance to extend the rotor’s service life. Additionally, the entire rotor is coated with a rust-resistant layer to protect against environmental elements. With a nominal thickness of 34 mm and a discard thickness of 32.4 mm, this rotor meets the necessary specifications for safe operation and replacement intervals.

About the DFC Brake Rotor - Drilled and Slotted - Silver Line
