Details on the DFC Brake Rotor - Drilled and Slotted - Silver Line

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction offers a balance of durability and performance for disc brake systems. This product line focuses on rotors that feature both drilled holes and slots, which help reduce brake fade by improving heat dissipation and removing brake dust and gases. The silver zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life, especially in environments prone to rust.

Technical Specifications and Features

This rotor is vented to allow better airflow and cooling during braking, which is critical for maintaining consistent brake performance. The directional surface design ensures that the drilled holes and slots are oriented to maximize water and debris evacuation. With a nominal thickness of 18 mm and a discard thickness of 17 mm, this rotor maintains structural integrity while providing a clear wear limit for safety. The rotor’s four bolt holes and 110 mm bolt circle diameter match the Mazda RX-7’s specifications, ensuring proper fitment and secure installation.

Applications and Problem Solving

• Improves braking response and reduces brake fade in Mazda RX-7 vehicles
• Helps prevent rotor warping caused by excessive heat buildup
• Reduces brake dust accumulation on the rotor surface
• Minimizes corrosion with rust-resistant zinc silver hat finish
• Maintains consistent braking performance under wet conditions due to directional drilled and slotted design

Installation Notes and Tips

Ensure the rotor is installed on a compatible Mazda RX-7 model using the correct torque specifications for the four bolt holes. Verify that the rotor’s directional surface is oriented correctly to match the wheel rotation direction. Inspect the brake pads for wear and replace if necessary to maintain optimal contact with the rotor surface. Clean the rotor surface before installation to remove any protective coatings or residues.

Quality Assurance

Dynamite Friction manufactures this rotor to meet OEM specifications for fit and function. The rust-resistant coating and vented design contribute to the rotor’s durability and longevity. While no specific warranty information is provided, the product is designed to comply with industry standards for brake components used in Mazda RX-7 vehicles.
