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 brake pad bite and reduce heat buildup. The zinc silver coating on the rotor hat provides corrosion resistance, extending rotor life in various driving conditions. This product line is designed to meet the specific braking requirements of performance-oriented vehicles like the Lexus LS460 and Toyota Mirai.

Technical Specifications and Features

This disc brake rotor is vented to allow air circulation between the rotor surfaces, which helps prevent brake fade during extended use. The rotor’s directional slotted and drilled surface improves water and debris evacuation, enhancing braking response in wet or dusty environments. The rotor’s nominal thickness of 30 mm ensures durability, while the discard thickness of 27 mm indicates when replacement is necessary to maintain safety standards. The zinc silver hat finish offers rust resistance, protecting the rotor’s core components.

Applications and Problem Solving

• Compatible with Lexus LS460 and Toyota Mirai models requiring 335 mm diameter rotors
• Addresses brake fade caused by overheating during heavy braking
• Improves braking performance in wet or slippery conditions through slotted and drilled design
• Reduces rust and corrosion on rotor hats for longer service life
• Maintains consistent braking feel by preventing rotor warping

Installation Notes and Tips

Ensure the rotor is installed with the directional surface facing the correct rotation direction as indicated by the manufacturer. Verify bolt hole alignment with the 5-lug, 120 mm bolt circle diameter pattern specific to Lexus LS460 and Toyota Mirai. Measure rotor thickness before installation to confirm it meets or exceeds the discard thickness of 27 mm. Proper torque specifications should be followed to avoid rotor damage or uneven wear.

Quality Assurance

Dynamite Friction manufactures this rotor to meet OEM standards for fitment and performance. The rust resistant coating and vented design contribute to the rotor’s durability and reliability. While no specific warranty information is provided, adherence to discard thickness and installation guidelines will ensure optimal rotor lifespan and safety.
