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 rotor fade. The zinc silver hat finish provides corrosion resistance, extending rotor life, while the vented rotor design aids in heat dissipation during heavy braking. This product line is tailored for drivers seeking reliable, performance-oriented rotors for their vehicles.

Technical Specifications and Features

This disc brake rotor is vented to allow airflow between the rotor surfaces, which helps reduce heat buildup during braking. The rotor’s surface is both drilled and slotted, providing channels for gas and debris to escape, improving pad bite and reducing brake fade. The rotor has a nominal thickness of 28 mm and a discard thickness of 26 mm, ensuring safe replacement intervals. The zinc silver coating on the hat area offers rust resistance, while the plain disc finish maintains a clean braking surface. The rotor features 5 bolt holes with a bolt circle diameter of 114.3 mm and a center hole diameter of 60.1 mm, matching the specifications required for the Lexus LS400.

Common Applications and Problem Solving

• Replacement for worn or warped brake rotors on Lexus LS400
• Improves heat dissipation to reduce brake fade during heavy use
• Enhances braking performance in wet or dusty conditions with drilled and slotted design
• Prevents rust and corrosion on rotor hats for longer service life
• Maintains proper rotor thickness for safe braking operation

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 26 mm before installation. The rotor is directional, so install it following the indicated rotation direction for optimal performance. Verify bolt hole alignment with the 5-lug pattern and 114.3 mm bolt circle diameter specific to the Lexus LS400. Clean the rotor surface before installation to remove any protective coatings or residues. Proper torque specifications should be followed when securing the rotor to avoid warping.

Quality Assurance and Warranty

Dynamite Friction manufactures this rotor to meet OEM specifications for the Lexus LS400. The rust-resistant coating and vented design contribute to durability and consistent braking performance.
