• Outside diameter: 305 mm
• Directional slotted and drilled surface for improved cooling
• Hat finish in Geospec silver grey with rust-resistant coating
• 5 bolt holes with 12.6 mm diameter and 114.3 mm bolt circle diameter
• Center hole diameter: 69 mm
• Height: 71.5 mm

Detailed Product Features and Specifications

This disc brake rotor is specifically designed for the Kia Sorento, ensuring precise fitment and optimal braking performance. The rotor features a nominal thickness of 11 mm and a discard thickness of 9.4 mm, indicating when replacement is necessary to maintain safety standards. The 305 mm outside diameter and 71.5 mm height are engineered to match the vehicle's braking system requirements.

The rotor surface is both drilled and slotted in a directional pattern, which helps to reduce brake fade by improving heat dissipation and removing debris from the brake pad surface. The hat section is finished in Geospec silver grey and includes a rust-resistant coating to extend the rotor's service life and maintain appearance.

About the DFC Geoperformance Rotor - Drilled and Slotted Line

The DFC Geoperformance Rotor - Drilled and Slotted product line by Dynamite Friction focuses on rotors that combine drilled holes and slots in a directional pattern. This design supports enhanced braking efficiency by promoting better heat management and pad cleaning, which is particularly beneficial for vehicles like the Kia Sorento that may encounter varied driving conditions.

Applications and Problem Solving

• Compatible with Kia Sorento models requiring 305 mm diameter rotors
• Addresses brake fade caused by excessive heat buildup
• Helps reduce brake dust accumulation on rotor surface
• Improves wet weather braking performance by channeling water away
• Maintains braking consistency under heavy or repeated braking

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 9.4 mm before installation. Clean the rotor surface to remove any protective coatings or contaminants prior to mounting. Verify bolt hole alignment with the 5-lug pattern and 114.3 mm bolt circle diameter for proper fitment on the Kia Sorento. Use appropriate torque specifications for lug nuts to avoid rotor warping.
