Detailed Product Description

This Dynamite Friction rotor features a vented design that promotes efficient heat dissipation, reducing the risk of brake fade during extended use. The drilled and slotted surface improves pad bite and helps channel away water, dust, and gases generated during braking. The rotor’s plain disc finish combined with a zinc silver hat finish provides a balance of performance and corrosion resistance. With a bolt hole quantity of five and a bolt hole diameter of 13.5 mm, this rotor is engineered to fit securely on compatible vehicles. The directional surface type ensures optimal braking performance by directing debris away from the contact area.

The DFC Brake Rotor - Drilled and Slotted - Silver line from Dynamite Friction is designed to meet the demands of drivers seeking consistent braking performance with enhanced rotor longevity. This product line focuses on combining drilled and slotted rotor technology with corrosion-resistant finishes to maintain braking efficiency under various driving conditions.
