Details on the DFC Brake Rotor - Drilled and Slotted - Silver Line

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction is engineered to provide enhanced braking through a combination of drilled holes and slots on the rotor surface. This design improves heat dissipation and helps evacuate brake dust and gases, reducing brake fade during demanding driving conditions. The silver zinc coating on the rotor hat adds rust resistance, extending the rotor's service life. This rotor is directional, meaning it must be installed in the correct orientation to maximize performance and durability.
