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 precision slots to aid in gas and dust evacuation during braking. This design helps maintain consistent brake pad contact and reduces the risk of brake fade under demanding conditions. The black zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life while maintaining a clean appearance.

Technical Specifications and Features

This disc brake rotor is vented, allowing air to flow between the rotor surfaces to dissipate heat more effectively. The rotor's directional surface pattern is engineered to channel gases and debris away from the contact area, improving braking response. With a nominal thickness of 20 mm and a discard thickness of 18.4 mm, this rotor meets strict wear standards. The 5-lug bolt pattern with a 120 mm bolt circle diameter ensures compatibility with specified BMW models. The rotor's overall diameter of 330 mm and height of 69.1 mm align with factory specifications for proper fitment and performance.

Applications and Problem Solving

• Replaces worn or warped rotors on BMW 528i and 535i models
• Addresses brake fade caused by overheating during aggressive driving
• Improves braking consistency in wet or dusty conditions
• Reduces rust and corrosion on rotor hats with zinc black coating
• Enhances heat dissipation to extend brake pad life

Installation Notes and Tips

Ensure the rotor is installed on compatible BMW models listed to maintain proper fit and function. Verify that the rotor thickness is within discard limits before installation. Use appropriate torque specifications for the 5-lug bolt pattern with 16.6 mm diameter holes. Directional rotors must be installed following the indicated rotation direction to ensure optimal performance. Inspect brake pads and hardware during installation for best results.

Quality Assurance

Dynamite Friction manufactures this rotor to meet OEM standards for fit, form, and function. The rust-resistant zinc black finish on the rotor hat helps prevent corrosion, contributing to durability. While no specific warranty information is provided, the rotor is designed for reliable performance on BMW 5 Series vehicles including the 528i, 535i, and ActiveHybrid 5 models.
