Detailed Product Description

This Dynamite Friction DFC Brake Rotor - Drilled and Slotted - Silver is manufactured with a plain disc finish and a zinc silver coated hat to resist corrosion, extending rotor life in various driving conditions. The vented rotor design allows air to flow between the rotor surfaces, reducing heat buildup during braking. The directional slotted and drilled surface improves brake pad bite and helps channel away water, dust, and gases, which can degrade braking efficiency. With four bolt holes sized at 1/2-20 and a bolt circle diameter of 108 mm, this rotor is specifically designed to fit Ford Bobcat and Mercury Pinto models, ensuring proper alignment and secure installation.
