About the DFC Hi-Carbon Alloy GEOMET Coated Rotor Line

The DFC Hi-Carbon Alloy GEOMET Coated Rotor line by Dynamite Friction features rotors manufactured with a high-carbon alloy for enhanced wear resistance and thermal stability. The GEOMET coating provides corrosion protection, extending rotor life and maintaining performance under various driving conditions. This product line is designed to meet the specific braking requirements of vehicles like the Fiat 124 Spider and Mazda MX-5 Miata, ensuring compatibility and reliable operation.

Product Details and Specifications

This disc brake rotor is vented to allow better airflow and heat dissipation during braking, reducing the risk of brake fade. The nominal thickness of 22 mm ensures structural integrity, while the discard thickness of 20 mm indicates when the rotor should be replaced to maintain safety. The rotor’s outside diameter of 280 mm and inside diameter of 55 mm are tailored for the specified vehicle models. The four bolt holes, each 13.2 mm in diameter, provide a secure fit on the hub assembly. With a height of 44 mm, this rotor fits precisely within the brake caliper setup of the Fiat 124 Spider and Mazda MX-5 Miata.

Applications and Problem Solving

• Replacement for worn or warped rotors on Fiat 124 Spider and Mazda MX-5 Miata
• Improves braking consistency by reducing heat-related fade
• Addresses rotor corrosion issues with GEOMET coating
• Restores proper rotor thickness for safe braking performance
• Compatible with vented brake systems requiring precise rotor dimensions

Installation Notes and Tips

Ensure the rotor surface and hub are clean and free of debris before installation. Verify the rotor thickness is above the discard thickness of 20 mm before use. Use proper torque specifications for the four 13.2 mm bolt holes to secure the rotor. It is recommended to inspect brake pads and hardware during rotor replacement to maintain optimal braking system performance.

Quality Assurance and Warranty

Dynamite Friction manufactures the 900-80073 rotor to meet industry standards for durability and performance. The high-carbon alloy construction combined with the GEOMET coating provides resistance to wear and corrosion.
