Product Line Details: DFC Hi-Carbon Alloy GEOMET Coated Rotor

The DFC Hi-Carbon Alloy GEOMET Coated Rotor line by Dynamite Friction features rotors manufactured with a high-carbon alloy for enhanced wear resistance and thermal stability. The GEOMET coating provides corrosion protection, extending rotor life and maintaining performance under various driving conditions. This product line is tailored to deliver consistent braking performance while reducing the risk of rotor warping and corrosion, making it suitable for demanding applications such as those found in BMW X5 and X6 vehicles.

Technical Specifications and Features

This disc brake rotor is vented, which allows for better heat dissipation during braking, reducing the risk of brake fade. The rotor has a nominal thickness of 36 mm and a discard thickness of 34.4 mm, indicating when replacement is necessary to maintain safe braking. The outside diameter measures 365 mm, while the inside diameter is 75 mm, ensuring compatibility with the specified BMW models. It features five bolt holes, each with a diameter of 16.6 mm, and a rotor height of 62.4 mm, all critical dimensions for proper installation and fitment.

Applications and Problem Solving

• Replacement for worn or warped rotors on BMW X5 and X6
• Improves braking consistency and heat management
• Addresses rotor corrosion issues with GEOMET coating
• Reduces brake fade during heavy or repeated braking
• Restores proper rotor thickness for safe braking performance

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 34.4 mm before installation. Properly torque the five bolts with 16.6 mm diameter holes to manufacturer specifications. The vented design requires clearance for airflow, so verify fitment on BMW X5 and X6 models. It is recommended to replace brake pads simultaneously to optimize braking performance and rotor longevity.

Quality Assurance and Warranty

Dynamite Friction rotors undergo rigorous quality control to meet OEM standards for fitment and performance. The high-carbon alloy construction combined with GEOMET coating ensures durability and corrosion resistance. Warranty details should be confirmed with the distributor or manufacturer, as coverage may vary.
