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

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction focuses on rotors that combine drilled holes and slots on the braking surface. This design improves water and gas evacuation during braking, reducing fade and maintaining consistent stopping power. The black zinc-coated hat finish adds corrosion resistance, extending rotor life in various driving conditions. This product line is tailored for drivers seeking reliable, performance-oriented rotors for their vehicles.

Technical Specifications and Features

This disc brake rotor is a solid type with a nominal thickness of 10 mm and a discard thickness of 8 mm, ensuring a clear service limit for safety. The rotor measures 261 mm in outside diameter and 53 mm in overall height, with a center hole diameter of 66 mm. It includes 4 bolt holes and 4 stud/lug holes, both arranged on a 114.3 mm bolt circle diameter, compatible with Mazda RX-7 mounting specifications. The rotor surface is directional with a slotted and drilled pattern, designed to improve braking efficiency by allowing heat and debris to escape more effectively. The zinc black hat finish and rust-resistant coating help protect against corrosion, maintaining rotor integrity over time.

Applications and Problem Solving

• Replacement rotor for worn or warped Mazda RX-7 brake rotors
• Improves heat dissipation to reduce brake fade during aggressive driving
• Enhances wet weather braking by channeling water away from the rotor surface
• Addresses brake noise and vibration issues caused by uneven rotor surfaces
• Provides corrosion resistance to extend rotor service life

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 8 mm before installation. Clean the rotor surface to remove any protective coatings or oils prior to mounting. Verify bolt hole alignment with the Mazda RX-7 hub using the 114.3 mm bolt circle diameter. Properly torque all lug nuts to manufacturer specifications to avoid rotor warping. Directional rotors must be installed with the correct rotation direction for optimal performance.

Quality Assurance and Warranty

Dynamite Friction manufactures this rotor to meet OEM specifications for fit and function on Mazda RX-7 vehicles. The rust-resistant coating and zinc black hat finish contribute to durability and corrosion protection.
