Product Line Details: DFC Hi-Carbon Alloy GEOMET Coated Rotor - Drilled
The DFC Hi-Carbon Alloy GEOMET Coated Rotor - Drilled line by Dynamite Friction is designed to provide enhanced braking performance through the use of high-carbon alloy material combined with a GEOMET coating. This coating offers superior rust resistance compared to standard finishes, while the drilled surface pattern aids in heat dissipation and brake fade reduction. This rotor line is suitable for drivers seeking reliable stopping power and rotor longevity, particularly in performance-oriented vehicles like the Mercedes-Benz A35 AMG.
Technical Specifications and Features
This disc brake rotor is vented to allow better airflow and cooling during braking, which helps maintain consistent performance. The rotor’s X drilled surface type improves heat dissipation and reduces brake fade. The rotor has a nominal thickness of 32 mm and a discard thickness of 30 mm, ensuring it meets safety standards for wear limits. The hat features a GEOMET grey finish that provides rust resistance, extending the rotor’s service life. With 5 bolt holes and a bolt circle diameter of 112 mm, it fits securely on the specified vehicle. The rotor’s outside diameter measures 350 mm, and the height is 46.5 mm, matching the OEM specifications for the Mercedes-Benz A35 AMG.
Applications and Problem Solving
- Replacement for worn or warped rotors on Mercedes-Benz A35 AMG
- Improves heat management to reduce brake fade during aggressive driving
- Addresses corrosion issues with rust-resistant GEOMET coating
- Restores braking performance and pedal feel
- Compatible with vehicles requiring a 5-lug, 350 mm diameter vented rotor
Installation Notes and Tips
Ensure the rotor thickness is above the discard thickness of 30 mm before installation. Clean the hub surface to prevent uneven rotor mounting. Use proper torque specifications for the 5 lug bolts to avoid rotor warping. This rotor is non-directional, so it can be installed on either side of the vehicle without concern for rotation direction. Verify compatibility with the Mercedes-Benz A35 AMG model year and brake system before installation.
Quality Assurance
Dynamite Friction manufactures this rotor to meet or exceed OEM standards for fit, form, and function. The GEOMET coating provides enhanced corrosion resistance, contributing to longer rotor life. While no specific warranty information is provided, the rotor’s design and materials support reliable performance under normal operating conditions. Always consult vehicle service manuals and follow recommended maintenance schedules for optimal results.
