Overview of Dynamite Friction DFC Hi-Carbon Alloy GEOMET Coated Rotor

The Dynamite Friction DFC Hi-Carbon Alloy GEOMET Coated Rotor (part number 900-31050) is engineered for BMW M3 and M5 models requiring reliable braking performance. This vented disc brake rotor is designed to maintain optimal thickness and heat dissipation under demanding driving conditions.

  • Nominal thickness: 20 mm
  • Discard thickness: 18.4 mm
  • Outside diameter: 327 mm
  • Inside diameter: 75 mm
  • Bolt hole diameter: 14.6 mm
  • Bolt hole quantity: 5
  • Height: 61.7 mm
  • Vented rotor design for improved cooling

Detailed Product Features and Specifications

This disc brake rotor features a vented design that enhances heat dissipation, reducing the risk of brake fade during extended use. The nominal thickness of 20 mm ensures structural integrity, while the discard thickness of 18.4 mm indicates the minimum safe thickness before replacement is necessary. With an outside diameter of 327 mm and an inside diameter of 75 mm, this rotor is specifically sized for BMW M3 and M5 vehicles. The rotor includes five bolt holes with a diameter of 14.6 mm, compatible with the factory bolt pattern. The height of 61.7 mm supports proper fitment and alignment within the brake assembly.

About the DFC Hi-Carbon Alloy GEOMET Coated Rotor Line

The DFC Hi-Carbon Alloy GEOMET Coated Rotor line from 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 wear. The high-carbon alloy construction improves rotor durability and helps maintain consistent braking performance over time, making it suitable for performance-oriented BMW M3 and M5 models.

Applications and Problem Solving

  • Replacement for worn or warped rotors on BMW M3 and M5
  • Improves heat dissipation to reduce brake fade during aggressive driving
  • Restores braking performance compromised by rotor thickness below discard limit
  • Addresses rotor corrosion issues with GEOMET coating protection
  • Ensures proper fitment with exact bolt hole pattern and dimensions

Installation Notes and Tips

When installing the Dynamite Friction 900-31050 rotor, ensure the rotor surface is clean and free of any contaminants. Verify the bolt hole alignment matches the vehicle’s hub assembly. It is recommended to replace brake pads simultaneously to maintain optimal braking performance. Torque bolts to manufacturer specifications and check rotor thickness regularly to monitor wear.

Quality Assurance and Warranty

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