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 design improves airflow to reduce heat buildup during braking, while the drilled and slotted surface helps evacuate gases, dust, and water for consistent stopping power. The directional surface pattern ensures proper rotation and maximizes performance. The rotor’s zinc black hat finish provides corrosion resistance, extending the rotor’s service life. With a nominal thickness of 19.9 mm and a discard thickness of 18.4 mm, this rotor maintains structural integrity under demanding conditions. The 5-bolt hole configuration with a 120 mm bolt circle diameter matches the factory specifications for the listed BMW models.

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.
