Detailed Product Description

The DFC Geoperformance Rotor - Drilled and Slotted by Dynamite Friction is designed to meet the braking demands of Chrysler and Dodge performance vehicles such as the 300, Challenger, Charger, and Magnum. This rotor features a vented design that improves heat dissipation during heavy braking, reducing the risk of brake fade. The directional surface is both drilled and slotted, which helps to evacuate gases, dust, and water from the braking surface, maintaining consistent pad contact and improving stopping power.

The rotor’s nominal thickness is 28.1 mm with a discard thickness of 26.5 mm, ensuring a long service life before replacement is necessary. The rotor’s outside diameter measures 345 mm, with an overall height of 54.8 mm, making it compatible with the specified vehicle models. The hat section is finished in Geospec silver grey, providing corrosion resistance along with a rust-resistant coating applied to the entire rotor surface to extend durability.

DFC Geoperformance Rotor - Drilled and Slotted Product Line

The DFC Geoperformance Rotor - Drilled and Slotted line focuses on delivering rotors that balance performance and reliability. This product line incorporates vented rotors with directional drilled and slotted surfaces to optimize braking under demanding conditions. The design is intended to improve heat management and maintain consistent braking performance, making it suitable for Chrysler and Dodge vehicles requiring enhanced rotor functionality.

Applications and Problem Solving

• Reduces brake fade during aggressive driving or towing
• Improves wet weather braking by channeling water away from the rotor surface
• Minimizes brake dust buildup for cleaner operation
• Enhances heat dissipation to prevent rotor warping
• Maintains consistent braking performance under heavy load conditions

Installation Notes and Tips

Ensure the rotor is installed on compatible Chrysler or Dodge models such as the 300, Challenger, Charger, or Magnum. Verify the bolt hole pattern matches the vehicle’s hub (5 bolt holes, 16.9 mm diameter, 115 mm bolt circle diameter). Clean the rotor surface before installation to remove any protective coatings or residues. Use proper torque specifications for lug nuts to avoid rotor damage or uneven wear.

Quality Assurance

Dynamite Friction rotors are manufactured to meet or exceed OEM specifications. The rust-resistant coating and Geospec silver grey hat finish contribute to long-term durability. While specific warranty details are not provided, Dynamite Friction products are designed for reliable performance and consistent quality in automotive braking applications.
