Detailed Product Description

This Dynamite Friction DFC Brake Rotor - Drilled and Slotted - Silver is specifically designed to meet the braking demands of Ford, Lincoln, and Mercury vehicles including the Mustang, Continental, Capri, and Mark VII. The rotor features a vented design that improves airflow to reduce heat buildup during braking, which helps maintain consistent stopping power and reduces the risk of brake fade. The drilled and slotted surface enhances water and debris evacuation from the rotor face, improving wet weather braking performance and pad bite.

The rotor’s directional surface ensures proper rotation for optimal performance, while the zinc silver coating on the hat provides corrosion resistance to extend the rotor’s service life. With a nominal thickness of 24 mm and a discard thickness of 22.75 mm, this rotor maintains structural integrity under demanding conditions. The 5-bolt hole pattern with a 114.3 mm bolt circle diameter matches factory specifications for precise fitment.
