Detailed Product Description
The DFC Brake Rotor - Drilled and Slotted - Silver from Dynamite Friction is a vented disc brake rotor designed to improve braking efficiency and durability. Its drilled and slotted surface helps to reduce brake fade by allowing gases and debris to escape, while the vented design promotes better heat dissipation during heavy braking. The rotor features a nominal thickness of 23.86 mm and a discard thickness of 22.23 mm, ensuring a long service life before replacement is necessary.
The rotor’s hat is finished in zinc silver, providing corrosion resistance, complemented by an overall rust-resistant coating to extend the rotor’s lifespan. The directional surface pattern is engineered to optimize braking performance and pad contact. With a bolt hole diameter of 1/2-20 and a 5-bolt pattern on a 114.3 mm bolt circle diameter, this rotor is compatible with specific Ford and Mercury vehicles, including the Mustang, Cougar, and Montego.
