Detailed Product Description

The DFC Brake Rotor - Drilled and Slotted - Black from Dynamite Friction is designed to meet the specific braking requirements of select BMW vehicles. Its vented construction allows for efficient heat dissipation during braking, reducing the risk of brake fade under demanding conditions. The rotor’s directional slotted and drilled surface helps to evacuate gases, dust, and water, maintaining consistent brake pad contact and improving overall stopping power.

The rotor features a plain disc finish combined with a zinc black hat finish that provides corrosion resistance and durability. The rust resistant coating further protects the rotor from environmental elements, extending its service life. With a nominal thickness of 22 mm and a discard thickness of 20.4 mm, this rotor maintains structural integrity and safety standards throughout its lifespan.

DFC Brake Rotor - Drilled and Slotted - Black Product Line

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction focuses on rotors that combine drilled holes and slots with a corrosion-resistant black zinc finish on the hat. This product line is engineered to provide enhanced heat dissipation and improved braking performance while offering protection against rust and wear.
