Product Line Details: DFC Brake Rotor - Drilled and Slotted - Black

The DFC Brake Rotor - Drilled and Slotted - Black line from Dynamite Friction offers rotors designed with both drilled holes and slots to improve brake pad bite and reduce heat buildup. The black zinc coating on the rotor hat provides corrosion resistance, extending rotor life in various driving conditions. This product line focuses on solid rotors with directional surfaces, suitable for drivers seeking enhanced braking control on specific Fiat and Mazda models.

Technical Specifications and Features

This disc brake rotor is constructed as a solid rotor with a nominal thickness of 9.5 mm and a discard thickness of 7.5 mm, ensuring safe replacement intervals. The rotor's surface is both drilled and slotted, which helps evacuate gases and debris from the brake pad interface, reducing brake fade during aggressive driving. The directional surface design optimizes airflow and cooling efficiency. The rotor hat is finished with a rust-resistant zinc black coating to protect against corrosion. It features 4 bolt holes with a 100 mm bolt circle diameter and a center hole diameter of 55 mm, matching the factory specifications for the Fiat 124 Spider and Mazda MX-5 Miata.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Fiat 124 Spider and Mazda MX-5 Miata
• Improves heat dissipation to reduce brake fade during spirited driving
• Helps maintain consistent braking performance under heavy use
• Addresses rotor corrosion issues with rust-resistant coating
• Enhances brake pad bite and debris removal with drilled and slotted surface

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 7.5 mm before installation. Clean the rotor surface to remove any protective coatings or residues before mounting. Verify bolt hole alignment with the 4-lug, 100 mm bolt circle pattern specific to the Fiat 124 Spider and Mazda MX-5 Miata. Proper torque specifications should be followed to avoid rotor warping. Directional rotors must be installed with the correct rotation direction for optimal performance.

Quality Assurance

Dynamite Friction manufactures the 633-80072R rotor to meet OEM standards for fit and function. The rust-resistant zinc black finish on the rotor hat enhances durability against corrosion. While no specific warranty information is provided, the rotor is designed to maintain structural integrity and braking performance within the specified thickness limits.
