Details on the DFC Brake Rotor - Drilled and Slotted - Silver Line

The DFC Brake Rotor - Drilled and Slotted - Silver line from Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and reduce heat buildup. This product line is designed to provide consistent braking performance while helping to minimize brake fade, making it suitable for drivers of Genesis G80, Hyundai Genesis, and Kia K900 models who require dependable stopping power.

Technical Description and Specifications

This solid disc brake rotor features a 314 mm outside diameter and a 61 mm overall height, fitting vehicles with a 5-lug bolt pattern and 114.3 mm bolt circle diameter. The rotor’s surface is both drilled and slotted, which aids in channeling away gases and debris from the brake pad interface, enhancing braking response. The zinc silver hat finish and rust resistant coating protect the rotor from corrosion, extending its service life. The nominal thickness of 13 mm ensures structural integrity, while the discard thickness of 11.4 mm indicates when replacement is necessary to maintain safe braking performance.

Compatible Vehicles and Common Applications

• Replacement rotor for Genesis G80 models requiring drilled and slotted rotors
• Suitable for Hyundai Genesis vehicles needing corrosion-resistant brake rotors
• Fits Kia K900 models with 5-lug, 114.3 mm bolt circle diameter
• Addresses issues such as brake fade during heavy use
• Helps reduce brake noise and vibration caused by uneven rotor surfaces

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 11.4 mm before installation. Properly clean the rotor surface to remove any protective coatings or debris. Verify bolt hole alignment with the vehicle’s hub using the 5-bolt, 12.5 mm diameter holes and 114.3 mm bolt circle diameter. Follow manufacturer torque specifications for lug nuts to avoid rotor warping. Directional rotors must be installed with the correct rotation direction for optimal performance.
