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

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction focuses on rotors that combine drilled holes and slots with a black zinc-coated hat for corrosion resistance. This product line is designed to provide enhanced braking performance through improved heat dissipation and debris removal, making it suitable for BMW vehicles requiring reliable and consistent braking under various driving conditions.

Technical Specifications and Features

This disc brake rotor is vented to allow air circulation between the rotor surfaces, which helps maintain optimal operating temperatures during braking. The directional surface pattern, featuring both drilled holes and slots, aids in expelling gases, dust, and water from the braking surface, reducing the risk of brake fade and maintaining consistent pad contact. The rotor's nominal thickness is 25 mm, with a discard thickness of 23.4 mm, ensuring safe replacement intervals. The zinc black finish on the hat section provides rust resistance, extending the rotor's service life. With 5 bolt holes sized at 14.6 mm and a bolt circle diameter of 120 mm, this rotor fits securely on compatible BMW models.

Applications and Problem Solving

• Improves braking performance on BMW 330Ci, 330i, 330xi, and Z4 models
• Reduces brake fade during aggressive or prolonged braking
• Helps prevent rotor warping caused by excessive heat buildup
• Minimizes corrosion with rust-resistant coating
• Maintains consistent brake pad contact for smoother stops

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 23.4 mm before installation. Clean the rotor surface to remove any protective coatings or contaminants prior to mounting. Verify bolt hole alignment with the vehicle’s hub using the 5 bolt holes and 120 mm bolt circle diameter. Proper torque specifications should be followed to avoid rotor distortion. Directional rotors must be installed with the rotation arrow pointing in the correct direction of wheel rotation for optimal performance.

Quality Assurance

Dynamite Friction manufactures this rotor to meet OEM specifications for fitment and performance on BMW 330Ci, 330i, 330xi, and Z4 models. The rust-resistant zinc black finish and vented design contribute to durability and longevity. While no specific warranty information is provided, the rotor is engineered to maintain structural integrity and braking efficiency within recommended service intervals.
