Designed as a vented disc brake rotor, it offers reliable heat dissipation and consistent stopping power for vehicles such as the BMW 120i, 125i, 128i, 323i, 325i, 325xi, 328i, and 328xi.

• Nominal thickness of 24 mm with a discard thickness of 22.4 mm
• Vented rotor design for improved heat management
• 300 mm outside diameter and 79 mm inside diameter
• Five bolt holes with a 14.7 mm diameter each
• Height of 73.8 mm for proper fitment

Detailed Specifications and Features

This disc brake rotor features a vented design that enhances airflow to reduce heat buildup during braking, which is critical for maintaining brake efficiency and rotor longevity. The rotor’s nominal thickness is 24 mm, with a discard thickness of 22.4 mm, indicating when replacement is necessary to maintain safe braking performance. The 300 mm outside diameter and 79 mm inside diameter ensure compatibility with the specified BMW models. The rotor includes five bolt holes, each measuring 14.7 mm in diameter, facilitating secure mounting. With a height of 73.8 mm, this rotor fits precisely within the brake assembly of the compatible vehicles.

About the DFC GEOSPEC Coated Rotor Line

The DFC GEOSPEC Coated Rotor line by Dynamite Friction is designed to provide enhanced corrosion resistance and durability through a specialized coating process. This coating helps protect the rotor surface from rust and environmental wear, which is particularly beneficial for vehicles exposed to varying weather conditions. The 604-31067 rotor benefits from this coating, contributing to longer service life and consistent braking performance on BMW 120i, 125i, 128i, 323i, 325i, 325xi, 328i, and 328xi models.

Applications and Problem Solving

• Replacement for worn or warped rotors causing brake vibration
• Improves braking consistency in BMW 3 Series and 1 Series models
• Addresses rotor corrosion issues with coated surface protection
• Restores proper rotor thickness for safe braking performance
• Enhances heat dissipation to reduce brake fade during extended use

Installation Notes and Tips

Ensure the rotor is installed on compatible BMW models listed to maintain proper fitment. Verify the rotor thickness before installation to confirm it meets or exceeds the discard thickness of 22.4 mm. Clean the rotor surface and hub mounting area to prevent uneven contact. Use the correct torque specifications for the five 14.7 mm bolt holes to secure the rotor firmly. It is recommended to replace brake pads simultaneously to optimize braking performance.

Quality Assurance and Warranty

Dynamite Friction manufactures the 604-31067 rotor to meet industry standards for safety and durability. The DFC GEOSPEC Coated Rotor line undergoes quality control processes to ensure consistent dimensions and coating integrity. Warranty details should be confirmed with the distributor or manufacturer, as coverage may vary based on application and usage conditions.
