Detailed Product Description

This Dynamite Friction disc brake rotor is part of the DFC Geoperformance Rotor - Drilled and Slotted line, which focuses on delivering enhanced braking efficiency through advanced rotor surface technology. The drilled and slotted design helps evacuate gases, dust, and water from the braking surface, reducing brake fade and improving pedal feel. The vented rotor construction allows for better heat dissipation during heavy braking, which is critical for maintaining rotor integrity and brake performance over time.

The rotor’s nominal thickness is 22 mm, with a discard thickness of 20 mm, ensuring a long service life before replacement is necessary. The rotor features a plain disc finish combined with a Geospec silver grey hat finish that provides rust resistance and corrosion protection, extending the rotor’s durability in various driving conditions. The five-bolt hole pattern with a 114.3 mm bolt circle diameter and 12.4 mm stud hole diameter ensures a secure and precise fit on Mitsubishi Lancer models.

Applications and Problem Solving

• Reduces brake fade during aggressive or repeated braking
• Improves heat dissipation to prevent rotor warping
• Minimizes brake dust buildup for cleaner braking surfaces
• Enhances wet weather braking performance by channeling water away
• Provides corrosion resistance to extend rotor lifespan

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it meets the minimum discard thickness of 20 mm. Properly clean the rotor surface to remove any protective coatings or residues before mounting. Verify the bolt hole alignment with the vehicle’s hub and torque lug nuts to manufacturer specifications. It is recommended to replace brake pads when installing new rotors to optimize braking performance.

Quality Assurance

Dynamite Friction rotors undergo rigorous quality control to meet industry standards for safety and performance. The rust resistant coating and precision machining contribute to consistent braking and long-term durability. Warranty information is available through the manufacturer or authorized distributors.
