DFC GEOSPEC Coated Rotor Product Line Details

The DFC GEOSPEC Coated Rotor line by Dynamite Friction focuses on rotors with specialized coatings to resist corrosion and extend service life. This coating helps maintain rotor integrity under various driving conditions, making it suitable for BMW models requiring consistent braking performance. The vented design further aids in managing heat buildup during braking.

Technical Specifications and Features

This disc brake rotor features a vented design that enhances airflow to reduce heat and prevent brake fade during extended use. The nominal thickness of 19 mm ensures structural strength, while the discard thickness of 17.4 mm indicates the minimum safe thickness before replacement is necessary. The rotor measures 276 mm in outside diameter and 75 mm inside diameter, fitting precisely on the specified BMW models. It includes five bolt holes, each with a diameter of 14.6 mm, and a rotor height of 60 mm, ensuring compatibility and secure mounting.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on BMW 320i, 323Ci, 323i, and 328i
• Addresses brake noise and vibration issues caused by uneven rotor surfaces
• Helps restore braking efficiency and pedal feel
• Prevents overheating and brake fade with vented rotor design
• Corrosion resistance reduces rotor surface degradation over time

Installation Notes and Tips

When installing the Dynamite Friction 604-31042 rotor, ensure the rotor surface is clean and free of debris before mounting. Verify the bolt hole alignment with the vehicle hub and torque bolts to manufacturer specifications. It is recommended to replace brake pads simultaneously to optimize braking performance. Check rotor thickness regularly and replace when it reaches the discard thickness of 17.4 mm.

Quality Assurance and Warranty

Dynamite Friction manufactures the DFC GEOSPEC Coated Rotor 604-31042 to meet OEM standards for fit and function on BMW 320i, 323Ci, 323i, and 328i models.
