Product Line Details: DFC Brake Rotor - Drilled and Slotted - Silver

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 silver zinc coating on the rotor hat provides corrosion resistance, extending rotor life. This product line is designed to meet the demands of drivers who require consistent braking performance and durability, particularly for Acura RL applications.

Technical Specifications and Features

This disc brake rotor is vented to allow better airflow and heat dissipation, which helps prevent brake fade during extended use. The rotor's surface is both drilled and slotted, enhancing water and debris evacuation from the braking surface. The directional design ensures optimal contact with brake pads, improving braking efficiency. The rotor has a nominal thickness of 28 mm and a discard thickness of 26 mm, indicating when replacement is necessary to maintain safety. The zinc silver finish on the rotor hat offers rust resistance, protecting the rotor from corrosion over time.

Applications and Problem Solving

• Replacement rotor for worn or warped Acura RL brake rotors
• Improves heat dissipation to reduce brake fade during heavy braking
• Helps maintain consistent braking performance in wet or dirty conditions
• Addresses rotor corrosion issues with rust-resistant coating
• Restores 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. Clean the rotor surface to remove any protective coating or debris prior to mounting. Verify bolt hole alignment with the 5-lug, 120 mm bolt circle diameter pattern on the Acura RL. Use proper torque specifications for lug nuts to avoid rotor warping. Directional rotors should be installed following the indicated rotation direction for optimal performance.

Quality Assurance

Dynamite Friction manufactures this rotor to meet or exceed OEM specifications for the Acura RL. The rust-resistant zinc silver finish and vented design contribute to long service life. While no specific warranty information is provided, the rotor's design and materials support reliable braking performance under normal operating conditions.
