Detailed Product Features and Specifications

This DFC Brake Rotor features a 325 mm outside diameter and a nominal thickness of 12 mm, ensuring durability and consistent braking performance. The rotor’s surface is both drilled and slotted in a directional pattern, which helps to reduce brake fade by improving heat dissipation and removing debris from the brake pad surface. The hat section is finished in zinc black, providing corrosion resistance and extending the rotor’s service life. With a rust-resistant coating applied, this rotor is designed to withstand environmental exposure and maintain structural integrity.

The rotor includes five bolt holes with a diameter of 12.6 mm and a bolt circle diameter of 114.3 mm, matching the factory specifications for Hyundai K5 and Kia Sonata models. The center hole diameter measures 76 mm, ensuring proper alignment during installation. The discard thickness is set at 10 mm, which serves as a critical indicator for rotor replacement to maintain safe braking performance.

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

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction focuses on rotors that combine drilled holes and slots in a directional pattern to optimize braking efficiency.
