Detailed Product Description
This Dynamite Friction rotor is part of the DFC Geoperformance Rotor - Drilled and Slotted line, which focuses on delivering rotors with enhanced surface technology for improved braking efficiency. The drilled and slotted surface helps evacuate gases, dust, and water from the braking surface, reducing brake fade and improving pad contact. The vented rotor design further aids in heat dissipation, which is critical for maintaining braking performance during repeated or heavy braking scenarios.
The rotor's nominal thickness is 26.1 mm, with a discard thickness of 24.5 mm, ensuring a long service life before replacement is necessary. The rotor features a rust resistant coating and a Geospec silver grey finish on the hat, providing corrosion resistance and a clean appearance. The 350 mm outside diameter and 67.2 mm height are designed to meet exact fitment specifications for Dodge Charger models, ensuring proper installation and function.
Applications and Problem Solving
- Reduces brake fade during high-performance or heavy braking
- Improves heat dissipation to prevent rotor warping
- Enhances braking response with directional slotted and drilled surface
- Protects against rust and corrosion for longer rotor life
- Maintains consistent braking performance in wet or dusty conditions
Installation Notes and Tips
Ensure the rotor is installed on compatible Dodge Charger models matching the bolt pattern of 5 lug holes with a 114.3 mm bolt circle diameter. Verify the rotor thickness before installation to confirm it meets the minimum discard thickness of 24.5 mm. Proper torque specifications should be followed when securing the rotor to avoid warping. It is recommended to inspect brake pads and other braking components during installation to ensure optimal system performance.
