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 slots to improve water, gas, and dust evacuation from the braking surface. This design helps maintain consistent braking performance and reduces the risk of brake fade. 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 disc brake rotor is vented to allow better airflow and heat dissipation, which is critical for maintaining braking efficiency during extended use. The rotor’s nominal thickness is 30 mm, with a discard thickness of 28 mm, indicating when replacement is necessary to maintain safety. The rotor features a directional surface type with both drilled holes and slots, enhancing braking response and reducing brake dust buildup. The zinc silver hat finish offers rust resistance, protecting the rotor’s core components. The rotor is designed with five bolt holes and a bolt circle diameter of 114.3 mm, matching the Lexus LS430’s factory specifications.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Lexus LS430
• Improves heat dissipation to reduce brake fade during heavy braking
• Helps maintain consistent braking performance in wet or dusty conditions
• Reduces brake dust accumulation on wheels
• Prevents rust and corrosion on rotor hats for longer service life

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 28 mm before installation. Clean the rotor surface to remove any protective coatings or oils before mounting. Verify bolt hole alignment with the 5-lug pattern and 114.3 mm bolt circle diameter specific to the Lexus LS430. Use proper torque specifications for lug nuts to avoid rotor warping. It is recommended to replace brake pads simultaneously to ensure optimal braking performance.
