DFC Geoperformance Rotor - Drilled and Slotted Product Line

The DFC Geoperformance Rotor - Drilled and Slotted line by Dynamite Friction is designed to provide consistent braking performance with a focus on heat management and surface durability. The directional drilled and slotted surface pattern enhances pad contact and helps evacuate gases and debris, which is critical for maintaining braking efficiency. This rotor line features a vented design to improve airflow and reduce thermal stress, making it suitable for both daily driving and more demanding conditions.

Detailed Product Description

This disc brake rotor features a vented construction with an outside diameter of 345 mm and a height of 48.7 mm, optimized for Hyundai and Kia vehicles such as the K5, Palisade, and Sonata. The rotor’s surface is both drilled and slotted in a directional pattern, which improves braking response by increasing friction and allowing heat and gases to escape more efficiently. The rotor’s nominal thickness is 30 mm, with a discard thickness of 28 mm, ensuring a clear service life indicator for replacement. The hat section is finished in Geospec silver grey, providing corrosion resistance and a clean appearance. Additionally, the rotor is coated with a rust-resistant layer to extend its service life in various environmental conditions. The bolt hole diameter is 12.6 mm with 5 lug holes arranged on a 114.3 mm bolt circle diameter, ensuring precise fitment and secure mounting.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Hyundai K5, Palisade, and Sonata
• Improves braking performance by reducing brake fade during heavy use
• Addresses rotor corrosion issues with rust-resistant coating
• Enhances heat dissipation to prevent brake pad glazing and uneven wear
• Suitable for vehicles experiencing vibration or noise due to rotor surface damage

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify the bolt hole pattern and diameter match the vehicle specifications. Use proper torque settings on lug nuts to avoid rotor warping. It is recommended to replace brake pads when installing new rotors to maintain optimal braking performance. Check rotor thickness regularly and replace when it reaches the discard thickness of 28 mm.
