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 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 in vehicles like the Mitsubishi Lancer.

Technical Specifications and Features

This disc brake rotor is vented to allow air circulation between the rotor surfaces, which helps dissipate heat generated during braking. The rotor’s surface is both drilled and slotted, which aids in removing brake dust, gases, and water from the contact area, improving braking efficiency. The rotor has a nominal thickness of 22 mm and a discard thickness of 20.4 mm, ensuring safe replacement intervals. The zinc silver hat finish and rust-resistant coating protect against corrosion, maintaining structural integrity over time. The rotor features five bolt holes with a 114.3 mm bolt circle diameter and a center hole diameter of 90 mm, matching Mitsubishi Lancer specifications.

Applications and Problem Solving

• Restores braking performance on Mitsubishi Lancer models with worn or damaged rotors
• Reduces brake fade caused by overheating during aggressive driving or heavy braking
• Improves water and debris evacuation from the rotor surface for consistent braking in wet conditions
• Prevents rust and corrosion that can lead to rotor failure or uneven braking
• Maintains proper rotor thickness to ensure safe and effective braking

Installation Notes and Tips

Ensure the rotor surface is clean and free of any contaminants before installation. Verify that the rotor thickness is above the discard thickness of 20.4 mm before reuse. Use proper torque specifications for the 5 lug bolts with a 114.3 mm bolt circle diameter to secure the rotor. The directional slotted and drilled surface should be installed following the rotation direction indicated on the rotor to maintain optimal performance.

Quality Assurance

Dynamite Friction manufactures the 631-72036L rotor to meet or exceed OEM specifications for Mitsubishi Lancer vehicles. The rust-resistant zinc silver coating and vented design contribute to long service life and reliable braking. Warranty information is available through the manufacturer and should be consulted for specific coverage details.
