DFC GEOSPEC Coated Rotor Product Line Details

The DFC GEOSPEC Coated Rotor line by Dynamite Friction focuses on providing coated rotors that resist corrosion and wear, extending rotor life and maintaining consistent braking performance. This coating helps protect the rotor surface from rust, which is especially beneficial for vehicles exposed to moisture and road salts. The 604-31028 rotor is part of this line, combining solid rotor construction with protective coating to meet the braking demands of BMW 3 Series models.

Technical Specifications and Features

This disc brake rotor features a solid design with an outside diameter of 280 mm and a height of 60.1 mm, ensuring compatibility with the specified BMW models. The rotor includes five bolt holes, each with a diameter of 15 mm, and an inside diameter of 75 mm. The nominal thickness is 10 mm, with a discard thickness of 8.4 mm, indicating when the rotor should be replaced to maintain safe braking performance.

Applications and Problem Solving

• Replacement for worn or warped rotors on BMW 318i, 318is, 323i, 323is, 325i, 325is, 328i, and 328is
• Addresses brake pulsation caused by uneven rotor surfaces
• Helps reduce brake noise and vibration
• Prevents corrosion-related rotor damage with GEOSPEC coating
• Maintains consistent braking performance under normal driving conditions

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 8.4 mm before installation. Clean the hub surface and mounting area to prevent runout and ensure proper rotor seating. Use the correct torque specifications for the five 15 mm bolt holes to avoid warping. It is recommended to replace brake pads when installing new rotors to optimize braking efficiency.

Quality Assurance and Warranty

Dynamite Friction manufactures the DFC GEOSPEC Coated Rotor 604-31028 to meet industry standards for fitment and performance. The coating process enhances corrosion resistance, contributing to longer rotor life. Warranty details should be confirmed with the product documentation or supplier, as coverage may vary.
