• Nominal thickness of 30 mm with a discard thickness of 28.4 mm
• Vented rotor design for improved cooling
• Outside diameter of 332 mm and inside diameter of 75 mm
• Five bolt holes with a diameter of 16.4 mm
• Rotor height of 62.3 mm

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

The DFC Hi-Carbon Alloy GEOMET Coated Rotor line from Dynamite Friction features rotors with a high-carbon alloy composition and a GEOMET coating. This combination enhances rotor durability and corrosion resistance, making it suitable for vehicles like the BMW X5 and X6 that demand consistent braking performance. The coating also helps reduce brake dust and extends rotor life compared to standard rotors.

Technical Specifications and Features

This disc brake rotor is vented, allowing air to flow between the rotor surfaces to dissipate heat more effectively during braking. The nominal thickness of 30 mm ensures structural integrity, while the discard thickness of 28.4 mm indicates when the rotor should be replaced to maintain safe braking. The rotor measures 332 mm in outside diameter and 75 mm inside diameter, fitting precisely on the specified BMW models. The five bolt holes, each 16.4 mm in diameter, provide secure mounting, and the rotor height of 62.3 mm aligns with OEM specifications.

Applications and Problem Solving

• Replacement for worn or warped rotors on BMW X5 and X6
• Improves heat dissipation to reduce brake fade during heavy use
• Addresses rotor corrosion issues with GEOMET coating
• Restores braking performance affected by rotor thickness below discard limit
• Compatible upgrade for vented rotor systems requiring precise fitment

Installation Notes and Tips

Ensure the rotor is installed on compatible BMW X5 or X6 models matching the specified bolt pattern and dimensions. Clean the hub surface before installation to prevent runout. Torque bolts to manufacturer specifications and check rotor thickness regularly to avoid exceeding the discard thickness of 28.4 mm. Proper bedding-in of new rotors and pads is recommended for optimal performance.

Quality Assurance and Warranty

Dynamite Friction rotors undergo rigorous quality control to meet OEM standards for fitment and performance. The GEOMET coating provides additional corrosion resistance, contributing to longer rotor life. Warranty details should be confirmed with the distributor or manufacturer, as coverage may vary.
