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

The DFC Brake Rotor - Drilled and Slotted - Black line from Dynamite Friction offers rotors designed with both drilled holes and slots on the braking surface. This combination helps to reduce brake fade by allowing gases and debris to escape, while also improving water dispersion in wet conditions. The black zinc coating on the rotor hat provides additional protection against rust, making it suitable for daily driving conditions on Hyundai Kona and Kia Seltos models.

Technical Specifications and Features

This disc brake rotor is a solid type with a directional surface pattern, meaning the drilled and slotted design is optimized for rotation in a specific direction to maximize performance. The rotor has a nominal thickness of 10 mm and should be replaced once it reaches the discard thickness of 8 mm to maintain safe braking. The rotor’s bolt hole diameter and stud/lug hole diameter are both 12.5 mm, with a bolt circle diameter of 114.3 mm, matching the factory specifications for the listed vehicles. The overall diameter of 284 mm and height of 32.22 mm ensure proper fitment and clearance.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Hyundai Kona and Kia Seltos
• Improves brake cooling to reduce fade during heavy braking
• Helps prevent brake judder caused by uneven rotor surfaces
• Rust resistant coating addresses corrosion issues in humid or wet climates
• Directional drilled and slotted design aids in water and debris evacuation

Installation Notes and Tips

Ensure the rotor is installed with the directional surface facing the correct rotation direction as indicated on the rotor. Verify that the bolt hole pattern matches the vehicle’s hub assembly (5 bolts, 12.5 mm diameter, 114.3 mm bolt circle). Measure rotor thickness before installation and replace if below the discard thickness of 8 mm. Clean the rotor surface of any protective coatings or oils before installation to ensure optimal brake pad contact.
