Detailed Product Features and Specifications

This DFC Brake Rotor from Dynamite Friction is designed with a vented rotor type that helps maintain lower operating temperatures during braking, reducing the risk of brake fade. The rotor's surface is both drilled and slotted, which assists in expelling gases, dust, and water, improving overall braking consistency. The directional surface pattern is engineered to optimize the rotor's performance when installed in the correct orientation.

The rotor features a zinc black finish on the hat area, providing corrosion resistance and durability. Additionally, the entire rotor is coated with a rust-resistant layer to extend service life. With a nominal thickness of 22 mm and a discard thickness of 20.4 mm, this rotor meets precise wear specifications for safe operation. The bolt hole diameter and stud/lug hole diameter are both 14.6 mm, with a bolt circle diameter of 120 mm, ensuring proper fitment on compatible 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 to improve brake pad bite and heat dissipation. This product line is designed for drivers seeking enhanced braking performance and rotor longevity, particularly in vehicles like the BMW 525i and 528i. The black zinc finish adds corrosion protection while maintaining a clean, professional appearance.

Applications and Problem Solving

• Reduces brake fade caused by excessive heat buildup
• Improves wet weather braking by channeling water away from the rotor surface
• Minimizes brake dust accumulation for cleaner operation
• Prevents rotor warping through effective heat dissipation
• Restores braking performance on BMW 525i and 528i models with worn or damaged rotors

Installation Notes and Tips

Ensure the rotor is installed with the directional surface facing the correct rotation direction as indicated on the rotor. Verify that the bolt hole pattern (5 holes, 14.6 mm diameter, 120 mm bolt circle) matches your vehicle specifications. Measure rotor thickness before installation to confirm it meets or exceeds the discard thickness of 20.4 mm. Proper torque specifications should be followed when mounting the rotor to avoid warping or uneven wear.
