Detailed Product Description

The DFC Geoperformance Rotor - Drilled and Slotted by Dynamite Friction is designed specifically for the braking systems of Genesis G70 and Kia Stinger models. This rotor features a vented construction that helps dissipate heat more effectively during braking, reducing the risk of brake fade. The directional surface pattern combines drilled holes and slots to evacuate gases, dust, and water, which enhances braking consistency and performance in various driving conditions.

With a nominal thickness of 28 mm and a discard thickness of 26 mm, this rotor maintains structural integrity and safety throughout its service life. The rotor’s hat is finished in Geospec silver grey, providing corrosion resistance and a clean appearance. Additionally, the rotor is coated with a rust-resistant layer to protect against environmental wear, extending the rotor’s usable life.

DFC Geoperformance Rotor - Drilled and Slotted Product Line

The DFC Geoperformance Rotor - Drilled and Slotted line focuses on delivering rotors with enhanced surface designs that improve heat management and braking efficiency. This product line incorporates directional drilled and slotted rotors that are vented to optimize airflow and cooling. The combination of these features supports consistent brake performance, especially for performance-oriented vehicles like the Genesis G70 and Kia Stinger.

Common Applications and Problem Solving

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

Installation Notes and Tips

Ensure the rotor thickness is measured before installation; replace if below the discard thickness of 26 mm. Confirm compatibility with the vehicle’s bolt pattern (5 bolts, 114.3 mm bolt circle diameter) and center hole diameter (69 mm). Properly torque lug nuts to manufacturer specifications to avoid rotor damage. It is recommended to inspect brake pads and hardware during rotor replacement for optimal braking performance.

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 long-term durability. While specific warranty details are not provided, Dynamite Friction products are designed for reliable performance on Genesis G70 and Kia Stinger vehicles when installed and maintained according to manufacturer guidelines.
