Features of the DFC Brake Rotor - Drilled and Slotted - Silver

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction is designed to provide reliable braking with enhanced heat management. The drilled and slotted surface helps to reduce brake fade by allowing gases and debris to escape, while the vented rotor design improves airflow to maintain optimal operating temperatures. The zinc silver coating on the rotor hat offers corrosion resistance, extending the rotor's service life. This rotor is engineered with a directional surface pattern to ensure proper installation and consistent braking performance.

Technical Specifications and Design Details

This disc brake rotor has a nominal thickness of 30 mm and a discard thickness of 28 mm, indicating when replacement is necessary to maintain safe braking. The rotor's outside diameter measures 315 mm, with an overall height of 50.3 mm. It features five bolt holes with a bolt circle diameter of 114.3 mm and a center hole diameter of 62 mm, matching the Lexus LS430's specifications. The rotor surface is both drilled and slotted, which aids in heat dissipation and debris removal during braking. The vented rotor design further enhances cooling efficiency, reducing the risk of warping under heavy use.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Lexus LS430
• Improves heat dissipation to reduce brake fade during extended braking
• Helps maintain consistent braking performance under high-stress conditions
• Rust-resistant coating protects against corrosion in various environments
• Directional design ensures proper fit and optimal braking response

Installation Notes and Tips

When installing the Dynamite Friction DFC Brake Rotor (631-75009R) on a Lexus LS430, ensure the directional surface is oriented correctly according to the rotor markings. Verify that the rotor thickness is within the nominal range and replace if below the discard thickness of 28 mm. Clean the rotor surface before installation to remove any protective coatings or debris. Use proper torque specifications for the 5 lug bolts to ensure secure mounting and avoid rotor warping.
