Features and Specifications

The DFC Brake Rotor - Drilled and Slotted - Silver is designed with a vented rotor type to improve airflow and reduce heat buildup during braking. The rotor’s surface is both drilled and slotted, which helps to evacuate gases, dust, and water, maintaining consistent brake pad contact and reducing brake fade. The directional surface pattern is optimized for the Mitsubishi Lancer’s braking system, ensuring efficient stopping power.

The rotor has a nominal thickness of 22 mm and a discard thickness of 20 mm, indicating when replacement is necessary to maintain safety and performance. The zinc silver coating on the hat provides corrosion resistance, extending the rotor’s service life. The rotor features five bolt holes with a bolt circle diameter of 114.3 mm, matching the Mitsubishi Lancer’s hub specifications precisely.

DFC Brake Rotor - Drilled and Slotted - Silver Product Line

The DFC Brake Rotor - Drilled and Slotted - Silver line from Dynamite Friction focuses on rotors that combine drilled holes and slots with a corrosion-resistant finish. This product line is designed to provide enhanced heat dissipation and improved braking response for vehicles requiring reliable performance under varied driving conditions. The silver zinc coating on the rotor hat adds rust resistance, making it suitable for environments prone to moisture and road salt.

Applications and Problem Solving

• Reduces brake fade during aggressive or repeated braking
• Improves water and debris evacuation for consistent braking in wet conditions
• Helps maintain brake pad contact and performance
• Prevents rust and corrosion on the rotor hat for longer service life
• Compatible with Mitsubishi Lancer models requiring 330 mm diameter rotors

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 20 mm before installation. Clean the rotor surface to remove any protective coating or residue before mounting. Verify bolt hole alignment with the 5-lug pattern and 114.3 mm bolt circle diameter on the Mitsubishi Lancer hub. Proper torque specifications should be followed to avoid rotor warping or uneven wear.

Quality Assurance

Dynamite Friction manufactures the 631-72042L rotor to meet OEM specifications for fitment and performance on Mitsubishi Lancer vehicles. The rust-resistant zinc silver finish on the rotor hat helps extend durability. While no specific warranty information is provided, the rotor’s design and materials are intended to provide reliable braking performance when installed and maintained according to manufacturer guidelines.
