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

The DFC Brake Rotor - Drilled and Slotted - Silver is part of Dynamite Friction's DFC product line, which focuses on delivering rotors with enhanced surface designs to improve braking efficiency and rotor longevity. The drilled holes and slots help to reduce brake fade by allowing gases and heat to escape, while the directional pattern optimizes water and debris removal during wet conditions. The zinc silver coating on the rotor hat provides corrosion resistance, extending the rotor's service life.

Technical Specifications and Benefits

This disc brake rotor has a nominal thickness of 18 mm and a discard thickness of 16.5 mm, ensuring it meets safety standards for wear limits. The rotor's 338 mm outside diameter and 39.7 mm height are designed to match the OEM specifications for the listed Lexus models. The 5-bolt hole pattern with a 114.3 mm bolt circle diameter and 62 mm center hole diameter ensures precise fitment and secure mounting. The plain disc finish combined with the rust-resistant coating helps maintain rotor integrity under various driving conditions.

Common Applications and Problem Solving

• Replacement for worn or warped brake rotors on Lexus RX350, RX350L, RX450h, RX450hL
• Improves braking performance by reducing heat buildup and brake fade
• Addresses rotor corrosion issues with rust-resistant coating
• Enhances wet weather braking with directional drilled and slotted surface
• Restores proper rotor thickness for safe and reliable braking

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify the rotor thickness is above the discard thickness of 16.5 mm before mounting. Use proper torque specifications for the 5-bolt pattern to avoid warping. It is recommended to replace brake pads simultaneously to maintain optimal braking performance. Directional rotors must be installed with the correct rotation direction as indicated by the surface pattern.
