DFC Brake Rotor - Drilled and Slotted - Black Product Line

The DFC Brake Rotor - Drilled and Slotted - Black line from Dynamite Friction focuses on rotors that provide enhanced cooling and improved brake pad bite through a combination of drilled holes and precision slots. The black zinc coating on the rotor hat offers corrosion resistance, extending rotor life in various driving conditions. This product line is designed to meet the demands of performance-oriented drivers while maintaining compatibility with specific Genesis, Hyundai, and Kia models.

Technical Specifications and Features

This vented disc brake rotor features a 360 mm outside diameter and a nominal thickness of 30.1 mm, with a discard thickness of 28.4 mm to ensure safe replacement intervals. The rotor’s surface is both drilled and slotted, which helps to reduce brake fade by improving heat dissipation and removing brake dust and gases. The directional surface design optimizes braking efficiency and pad contact. The rotor hat is finished with a rust-resistant zinc black coating, while the disc surface has a plain finish to maintain consistent friction characteristics. It includes five bolt holes with a diameter of 12.4 mm and a bolt circle diameter of 114.3 mm, matching the stud/lug hole pattern for secure fitment.

Applications and Problem Solving

• Improves braking performance on Genesis G80, Equus, Genesis, and K900 models
• Reduces brake fade during heavy or repeated braking
• Helps prevent rotor warping caused by excessive heat buildup
• Minimizes rust and corrosion on rotor hats for longer service life
• Enhances pad bite and braking response with slotted and drilled design

Installation Notes and Tips

Ensure the rotor is installed on compatible Genesis, Hyundai, or Kia models as specified. Verify bolt hole alignment with the 5-lug pattern and 114.3 mm bolt circle diameter. Clean the rotor surface before installation to remove any protective coatings or residues. Use proper torque specifications for lug nuts to avoid rotor damage or uneven wear. It is recommended to replace brake pads when installing new rotors to maintain optimal braking performance.
