Detailed Product Features and Specifications

This DFC Brake Rotor - Drilled and Slotted - Silver is engineered with a 300mm outside diameter and a nominal thickness of 28mm, ensuring compatibility with specific Mercedes-Benz models including the 300SD, 300SDL, 300SE, 300SEL, 350SD, 350SDL, 420SEL, 560SEC, and 560SEL. The rotor features a vented design to improve heat dissipation during braking, reducing the risk of brake fade under demanding conditions.

The rotor surface is both drilled and slotted, which helps to evacuate gases, dust, and water, maintaining consistent brake pad contact and improving overall braking response. The directional surface design further enhances braking efficiency by channeling debris away from the rotor surface.

The hat section of the rotor is finished with a zinc silver coating, providing corrosion resistance and extending the rotor's service life. Additionally, the entire rotor is treated with a rust-resistant coating to protect against environmental wear.

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