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 on the braking surface. This design helps to reduce brake fade by improving heat dissipation and gas evacuation during braking. The black zinc coating on the rotor hat provides corrosion resistance, maintaining the rotor’s integrity and appearance over time. This product line is tailored for drivers seeking reliable braking components that meet OEM specifications for vehicles like the BMW X5.

Technical Specifications and Features

This rotor is a solid type, measuring 324 mm in outside diameter and 80.1 mm in overall height. It features a nominal thickness of 12 mm and a discard thickness of 10.4 mm, ensuring safe replacement intervals. The rotor includes 5 bolt holes with a diameter of 16.6 mm arranged on a 120 mm bolt circle diameter, matching the BMW X5’s hub specifications. The directional slotted and drilled surface improves braking efficiency by channeling away dust and gases, while the zinc black hat finish and rust-resistant coating protect against corrosion.

Applications and Problem Solving

• Replacement rotor for worn or warped BMW X5 brake rotors
• 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
• Restores braking surface integrity for smoother stopping power

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 10.4 mm before installation. Clean the hub surface thoroughly to prevent rotor runout. Use the correct torque specifications for the 5 lug bolts with 16.6 mm diameter on the 120 mm bolt circle. The directional surface requires installation in the correct rotation direction for optimal performance. Avoid contaminating the rotor surface with grease or oil during handling.
