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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and precision slots to optimize brake pad contact and heat dissipation. This product line is designed to provide consistent braking performance while minimizing rotor warping and brake fade. The silver zinc coating on the rotor hat offers additional corrosion resistance, extending the rotor's service life in various driving environments.

Technical Specifications and Features

This disc brake rotor is vented, allowing air to flow between the rotor surfaces to reduce heat buildup during braking. The directional surface pattern, featuring both drilled holes and slots, helps evacuate gases and debris from the brake pad interface, improving braking efficiency. The rotor has a nominal thickness of 18 mm and a discard thickness of 16 mm, ensuring safe replacement intervals. The rotor’s outside diameter measures 297 mm, with an overall height of 64 mm and a center hole diameter of 68 mm. It includes five bolt holes with a bolt circle diameter of 114.3 mm, matching the Nissan 300ZX specifications.

Common Applications and Problem Solving

• Replacement for worn or warped brake rotors on Nissan 300ZX
• Improves heat dissipation to reduce brake fade during aggressive driving
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Helps maintain consistent braking performance under heavy load or high-speed conditions
• Prevents rust and corrosion with zinc silver hat finish and rust-resistant coating

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 16 mm before installation. Clean the rotor surface to remove any protective coating or debris prior to mounting. Verify bolt hole alignment with the 5-lug pattern and 114.3 mm bolt circle diameter specific to the Nissan 300ZX. Proper torque specifications should be followed to avoid rotor warping. Directional rotors must be installed with the correct rotation direction for optimal performance.
