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 on the braking surface. This design improves water and gas evacuation during braking, reducing brake fade and maintaining consistent performance. The zinc silver coating on the rotor hat provides corrosion resistance, extending the rotor's service life. This product line is tailored for drivers seeking reliable braking components with enhanced heat management.

Technical Specifications and Features

This disc brake rotor is vented to allow better airflow and heat dissipation, which helps maintain braking efficiency under demanding conditions. The rotor’s nominal thickness is 28 mm, with a discard thickness of 26 mm, ensuring a clear service limit for safety. The rotor surface is finished plain with a directional pattern of slots and drilled holes, designed to channel away debris and moisture. The zinc silver hat finish offers rust resistance, protecting the rotor’s core structure. It features 5 bolt holes with a bolt circle diameter of 114.3 mm and a center hole diameter of 62 mm, matching the Lexus SC300 specifications precisely.

Common Applications and Problem Solving

• Replacement for worn or warped brake rotors on Lexus SC300
• Improves braking performance by reducing heat buildup and brake fade
• Helps prevent rust and corrosion on rotor hats for longer durability
• Addresses brake noise and vibration issues caused by uneven rotor surfaces
• Enhances wet weather braking through drilled and slotted surface design

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it is above the discard thickness of 26 mm. The directional surface requires correct orientation during installation to maintain optimal braking performance. Use proper torque specifications for the 5 lug bolts with a 114.3 mm bolt circle diameter. Clean the rotor surface of any protective coatings or oils before mounting to avoid brake pad contamination.
