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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction offers rotors designed with enhanced cooling and debris removal capabilities. The drilled holes and slots improve brake pad bite and reduce brake fade by allowing gases and heat to escape more efficiently. 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 a balance between performance and durability in their braking components.

Technical Specifications and Features

This disc brake rotor is vented to improve airflow and heat dissipation during braking, which helps maintain consistent braking performance. The rotor's nominal thickness is 32 mm, with a discard thickness of 29.8 mm, indicating when replacement is necessary to ensure safety. The rotor surface is both drilled and slotted, providing a directional braking surface that enhances pad cleaning and reduces brake fade. The rotor hat is finished with a rust-resistant zinc silver coating to protect against corrosion. It features five bolt holes with a bolt circle diameter of 114.3 mm and a center hole diameter of 69 mm, matching the Mitsubishi Lancer's specifications.

Applications and Problem Solving

• Replacement rotor for worn or warped Mitsubishi Lancer brake rotors
• Improves heat dissipation to reduce brake fade during aggressive driving
• Helps prevent brake pad glazing and maintains consistent braking performance
• Resists rust and corrosion for longer rotor life in various weather conditions
• Addresses vibration or noise issues caused by uneven rotor surfaces

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 29.8 mm before installation. Clean the rotor surface to remove any protective coating or debris prior to mounting. Verify bolt hole alignment with the vehicle’s hub using the 5-bolt pattern and 114.3 mm bolt circle diameter. Properly torque lug nuts to manufacturer specifications to avoid rotor warping. It is recommended to replace brake pads when installing new rotors to ensure optimal braking performance.

Quality Assurance

Dynamite Friction manufactures this rotor to meet or exceed OEM specifications for fit and function on Mitsubishi Lancer models. The rust-resistant zinc silver coating on the rotor hat enhances durability against corrosion. While no specific warranty information is provided, the rotor’s design and materials support reliable performance and longevity when installed and maintained properly.
