This vented disc brake rotor features a directional, slotted and drilled surface designed to enhance heat dissipation and maintain consistent stopping power under demanding conditions.

• Compatible with Mitsubishi Lancer vehicles
• Vented disc brake rotor with drilled and slotted surface
• Nominal thickness of 32 mm and discard thickness of 30 mm
• Silver zinc coating on the hat for corrosion resistance
• 5 bolt holes with a 114.3 mm bolt circle diameter
• Directional brake surface for optimized performance
• Overall diameter of 350 mm and height of 43.7 mm

Detailed Product Features and Specifications

This Dynamite Friction rotor is designed with a vented construction to improve airflow and reduce heat buildup during braking. The drilled and slotted surface helps evacuate gases, dust, and water, which can improve brake pad contact and reduce brake fade. The rotor’s nominal thickness is 32 mm, with a discard thickness of 30 mm, ensuring a long service life before replacement is necessary.

The rotor features a plain disc finish combined with a zinc silver coating on the hat, providing rust resistance and durability in various driving environments. It includes 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. The directional surface design is intended to optimize braking efficiency and pad wear.

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 for enhanced brake cooling and debris removal. This product line is tailored for drivers seeking rotors that maintain consistent braking performance under moderate to heavy use, such as daily driving or spirited driving conditions. The silver zinc coating on the rotor hats adds an extra layer of protection against corrosion, extending rotor life.

Applications and Problem Solving

• Reduces brake fade caused by heat buildup during repeated braking
• Improves wet weather braking by channeling water away from the rotor surface
• Minimizes brake dust accumulation for cleaner braking components
• Helps maintain consistent brake pad contact and performance
• Prevents premature rotor corrosion with rust-resistant coating

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 30 mm before installation. Clean the rotor surface to remove any protective coating or residue prior to mounting. Verify bolt hole alignment with the Mitsubishi Lancer’s hub using the 5-bolt pattern and 114.3 mm bolt circle diameter. Proper torque specifications should be followed to avoid rotor warping. Directional rotors must be installed with the correct rotation direction for optimal performance.

Quality Assurance and Warranty

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. While specific warranty details are not provided, Dynamite Friction products typically undergo rigorous quality control to ensure reliable braking performance.
