Detailed Product Specifications

This disc brake rotor features a vented design that enhances cooling during braking, reducing the risk of brake fade under heavy use. The rotor's nominal thickness is 28 mm, with a discard thickness of 26.4 mm, ensuring it can be resurfaced or replaced at the appropriate wear point. The outside diameter measures 328 mm, while the inside diameter is 75 mm, matching the hub size for a secure fit. It includes five bolt holes, each with a diameter of 16.65 mm, to align with the BMW X3 and X4 wheel hubs. The rotor height is 73.5 mm, which is critical for maintaining proper caliper clearance and brake system geometry.

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 material combined with a GEOMET coating. This coating provides corrosion resistance and extends rotor life by protecting against rust and environmental damage. The high-carbon alloy construction helps reduce brake noise and vibration, contributing to a smoother braking experience. This product line is designed to meet the performance and durability requirements of modern vehicles like the BMW X3 and X4.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on BMW X3 and X4
• Improves braking consistency and reduces brake fade
• Addresses rotor corrosion and surface rust issues
• Restores proper rotor thickness for safe braking
• Helps eliminate brake noise caused by uneven rotor wear

Installation Notes and Tips

Ensure the rotor is installed on compatible BMW X3 or X4 models using the correct torque specifications for the five bolt holes. Verify rotor thickness before installation; replace if below the discard thickness of 26.4 mm. Clean the rotor surface to remove any protective coatings or contaminants before mounting. It is recommended to replace brake pads simultaneously to maintain optimal braking performance.

Quality Assurance and Warranty

Dynamite Friction rotors, including part number 900-31151, are manufactured to meet industry standards for safety and durability. The GEOMET coating enhances corrosion resistance, contributing to longer service life.
