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 improve brake pad bite and reduce heat buildup. This product line is designed to provide enhanced braking consistency and resistance to brake fade, particularly useful for Nissan 240SX owners who demand dependable stopping power. The zinc silver hat finish adds corrosion resistance, extending rotor life in various environments.

Technical Specifications and Features

This disc brake rotor is a solid type with a nominal thickness of 9 mm and a discard thickness of 8 mm, ensuring it meets safety standards for wear limits. The rotor’s surface is both drilled and slotted, which helps evacuate gases and debris from the brake pad interface, improving braking efficiency. The rotor features a directional brake surface, which means it is designed to rotate in a specific direction to maximize performance. The zinc silver coating on the hat provides rust resistance, helping maintain structural integrity over time. With 5 bolt holes and a bolt circle diameter of 114.3 mm, it fits securely on the Nissan 240SX hub assembly.

Common Applications and Problem Solving

• Replacement for worn or warped brake rotors on Nissan 240SX
• Improves heat dissipation to reduce brake fade during aggressive driving
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Enhances braking response with slotted and drilled design
• Prevents rust and corrosion on rotor hats for longer service life

Installation Notes and Tips

Ensure the rotor is installed with the directional surface rotating correctly according to the vehicle’s forward motion. Verify that the bolt holes align with the hub’s bolt pattern (5 bolts, 114.3 mm bolt circle diameter). Measure rotor thickness before installation to confirm it meets or exceeds the discard thickness of 8 mm. Properly torque lug nuts to manufacturer specifications to avoid rotor warping. It is recommended to replace brake pads when installing new rotors to maintain optimal braking performance.
