About the DFC Hi-Carbon Alloy GEOMET Coated Rotor Line

The DFC Hi-Carbon Alloy GEOMET Coated Rotor line by Dynamite Friction incorporates a high-carbon alloy construction combined with a GEOMET coating. This coating offers corrosion resistance and extends rotor life by protecting against rust and environmental wear. The high-carbon alloy material improves rotor strength and heat tolerance, making it suitable for demanding braking applications in BMW X5 and X6 vehicles.

Applications and Problem Solving

• Replacement for worn or warped rotors on BMW X5 and X6
• Improves braking consistency under high heat conditions
• Reduces brake noise and vibration caused by rotor imperfections
• Prevents premature rotor corrosion and surface degradation
• Maintains proper rotor thickness for safe braking performance

Installation Notes and Tips

Ensure the rotor surface and hub are clean and free of debris before installation. Verify the rotor thickness is above the discard thickness of 18.4 mm before mounting. Use the correct torque specifications for the five 16.4 mm bolt holes to secure the rotor properly. It is recommended to replace brake pads simultaneously to ensure optimal braking performance. After installation, perform a brake bed-in procedure to maximize rotor and pad contact.
