Product Line Details: DFC Brake Rotor - Drilled and Slotted - Black

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction focuses on rotors that feature both drilled holes and slots on the braking surface. This combination is designed to improve brake pad bite and help evacuate gases, dust, and water during braking. The black zinc hat finish adds a layer of corrosion resistance, making these rotors suitable for demanding driving conditions. This product line is tailored for drivers seeking enhanced braking performance and durability on BMW X5 and X6 models.

Technical Specifications and Features

This disc brake rotor is vented to allow better airflow and heat dissipation, reducing the risk of brake fade during extended use. The rotor’s surface is both drilled and slotted, which helps maintain consistent braking performance by clearing debris and moisture from the pad contact area. The rotor has a nominal thickness of 30 mm and a discard thickness of 28.4 mm, ensuring a long service life before replacement is necessary.

The rotor’s bolt hole diameter is 16.4 mm with five bolt holes arranged on a 120 mm bolt circle diameter, matching the BMW X5 and X6 wheel hub specifications. The overall diameter of 332 mm and height of 62.3 mm ensure proper fitment and compatibility. The zinc black hat finish provides additional protection against rust and corrosion, extending the rotor’s durability.

Applications and Problem Solving

• Replacement rotor for worn or warped brake discs on BMW X5 and X6
• Improves heat dissipation to reduce brake fade during heavy braking
• Helps maintain consistent braking performance in wet or dusty conditions
• Addresses rotor corrosion issues with rust-resistant coating
• Enhances brake pad bite and reduces brake noise through drilled and slotted design

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (28.4 mm) before installation
• Verify bolt hole alignment with vehicle hub (5 holes, 16.4 mm diameter, 120 mm bolt circle)
• Clean hub surface before mounting to prevent uneven rotor seating
• Use proper torque specifications for lug nuts to avoid rotor warping
• Check brake pads for wear and replace if necessary to optimize rotor performance
