Detailed Product Description

This DFC Brake Rotor - Drilled and Slotted - Silver is part of Dynamite Friction's DFC line, which focuses on delivering rotors with enhanced surface designs to improve braking efficiency and rotor longevity. The drilled and slotted surface helps to reduce brake fade by allowing gases and heat to escape more effectively during braking. The directional pattern optimizes the rotor's performance by channeling heat and debris away from the contact surface.

Constructed with a nominal thickness of 11 mm and a discard thickness of 9 mm, this rotor ensures a balance between durability and performance. The zinc silver coating on the hat provides rust resistance, helping to maintain structural integrity and appearance over time. With a 305 mm outside diameter and 5 bolt holes sized at 12.6 mm, it fits securely on the specified Hyundai and Kia models.

Applications and Problem Solving

• Reduces brake fade during heavy or repeated braking
• Improves heat dissipation for consistent braking performance
• Minimizes rust and corrosion on the rotor hat
• Addresses uneven brake pad wear caused by heat buildup
• Enhances braking response for Hyundai Santa Fe and Kia Sorento vehicles

Installation Notes and Tips

Ensure the rotor surface is clean and free of any contaminants before installation. Verify that the rotor thickness is above the discard thickness of 9 mm to maintain safe braking performance. Use proper torque specifications for the 5 lug bolts to secure the rotor firmly. The directional slotted and drilled surface should be installed following the rotation direction indicated on the rotor to maximize effectiveness.

Quality Assurance

Dynamite Friction's DFC Brake Rotor line is manufactured to meet or exceed OEM specifications for fitment and performance. The rust-resistant coating and precision machining contribute to long-lasting durability. While no specific warranty information is provided, the product is designed for reliable service on Hyundai Santa Fe and Kia Sorento models when installed and maintained properly.
