Product Line Details: DFC Brake Rotor - Drilled and Slotted - Silver

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and reduce heat buildup. The silver zinc coating on the rotor hat provides corrosion resistance, extending rotor life. This product line is designed to meet the demands of daily driving and moderate performance needs, making it suitable for a range of Hyundai and Kia models requiring reliable stopping power.

Technical Specifications and Features

This disc brake rotor features a vented design with a 320 mm outside diameter and a 47.5 mm overall height, allowing for efficient heat dissipation during braking. The rotor surface is both drilled and slotted, which helps to evacuate gases, dust, and water, improving braking performance under various conditions. The rotor’s nominal thickness is 28 mm, with a discard thickness of 26.4 mm, ensuring clear service limits for maintenance. The zinc silver hat finish offers rust resistance, protecting the rotor’s core structure. The rotor is directional, meaning it is designed to rotate in a specific direction to maximize cooling and debris removal.

Compatible Vehicles and Applications

• Hyundai Azera
• Hyundai Sonata
• Hyundai Nexo
• Kia Cadenza
• Kia Optima
• Kia Sportage

This rotor is ideal for replacing worn or damaged rotors on these models, restoring braking efficiency and safety.

Common Issues Addressed by This Rotor

• Brake fade caused by overheating during extended braking
• Uneven rotor wear leading to vibration or noise
• Corrosion and rust buildup on rotor surfaces
• Reduced braking performance in wet or dusty conditions
• Warped rotors causing pedal pulsation

Installation Notes and Tips

Ensure the rotor is installed with the directional side facing the correct rotation direction as indicated on the rotor. Verify that the rotor thickness meets or exceeds the discard thickness of 26.4 mm before installation. Clean the rotor surface to remove any protective coatings or debris prior to mounting. Use proper torque specifications for the 5 bolt holes and lug nuts to avoid warping. It is recommended to replace brake pads simultaneously to ensure optimal braking performance.
