Detailed Product Description

This Dynamite Friction DFC Brake Rotor is specifically designed for Ford Mustang vehicles, providing a direct replacement rotor that meets OEM specifications. The vented rotor construction allows air to flow between the rotor faces, reducing heat buildup during braking. The drilled and slotted surface pattern is directional, which helps channel away water, dust, and brake dust, improving braking consistency and reducing the risk of brake fade. The rotor’s zinc silver hat finish and rust-resistant coating protect against corrosion, extending the rotor’s service life.

With a nominal thickness of 25 mm and a discard thickness of 23.5 mm, this rotor ensures safe and effective braking performance throughout its lifespan. The five bolt holes and stud/lug hole pattern with a 114.3 mm bolt circle diameter ensure compatibility with the Ford Mustang’s hub assembly. The rotor’s 330 mm outside diameter and 43.96 mm height are designed to match factory specifications for proper fit and function.

DFC Brake Rotor - Drilled and Slotted - Silver Product Line
