DFC Geoperformance Rotor - Drilled and Slotted Product Line

The DFC Geoperformance Rotor - Drilled and Slotted line focuses on enhanced braking efficiency through a combination of drilled holes and precision slots. This design improves heat dissipation and helps reduce brake fade under demanding conditions. The vented rotor construction further aids in cooling, making it suitable for vehicles requiring consistent braking performance, such as the Hyundai Elantra and Kia K5.

Detailed Product Description

This disc brake rotor features a 305 mm outside diameter and a nominal thickness of 25 mm, with a discard thickness of 23 mm to ensure safe replacement intervals. The rotor is vented to allow airflow between the braking surfaces, reducing heat buildup during braking. The drilled and slotted surface enhances water and debris evacuation, improving brake pad contact and reducing noise. The directional surface design ensures optimal performance when installed correctly. The rotor’s hat is finished in Geospec silver grey, providing corrosion resistance alongside a rust resistant coating applied to the entire rotor. The 5 bolt holes with a 12.5 mm diameter and 114.3 mm bolt circle diameter match the specifications for compatible Hyundai and Kia models.

Applications and Problem Solving

• Restores braking performance on Hyundai Elantra, Kona, Sonata and Kia K5, Kona Electric, Niro EV
• Reduces brake fade caused by overheating during extended braking
• Minimizes brake noise and vibration with slotted and drilled design
• Prevents rust and corrosion for longer rotor life
• Ensures consistent braking response with directional rotor surface

Installation Notes and Tips

• Verify rotor thickness before installation; replace if below 23 mm discard thickness
• Ensure correct directional orientation for optimal braking performance
• Clean rotor surface before installation to remove any protective coatings or debris
• Check compatibility with vehicle bolt pattern: 5 lug holes, 12.5 mm diameter, 114.3 mm bolt circle

Quality Assurance

Dynamite Friction rotors are manufactured to meet or exceed OEM specifications for fit, form, and function. The rust resistant coating and Geospec silver grey hat finish contribute to durability and corrosion resistance. While specific warranty details are not provided, Dynamite Friction products are designed for reliable, long-term use on compatible Hyundai and Kia vehicles.
