About the DFC Brake Rotor - Drilled and Slotted - Silver Line

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 heat dissipation. This design helps reduce brake fade and maintain consistent braking performance, especially for vehicles like the Hyundai Optima and Kia Sonata that require reliable stopping power in daily driving and moderate performance conditions.

Product Details and Specifications

This disc brake rotor features a vented design that allows air to flow between the rotor surfaces, enhancing cooling during braking. The drilled and slotted surface helps evacuate gases, dust, and water, which can accumulate between the brake pad and rotor, improving overall braking efficiency. The rotor’s zinc silver hat finish and rust-resistant coating provide additional protection against corrosion, extending the rotor’s service life. With a nominal thickness of 26 mm and a discard thickness of 24.4 mm, this rotor meets the necessary specifications for safe and effective brake operation.

Compatible Vehicles and Applications

• Hyundai Optima brake rotor replacement
• Kia Sonata disc brake rotor upgrade
• Addressing brake fade and overheating issues
• Replacing worn or warped rotors for improved braking
• Enhancing brake performance with vented, drilled, and slotted rotors

Installation Notes and Tips

Ensure the rotor surface is clean and free of any contaminants before installation. Verify that the rotor thickness is within the specified limits (nominal 26 mm, discard 24.4 mm) to maintain safe braking performance. Use the correct torque specifications for the 4 bolt holes with a 114.3 mm bolt circle diameter. This rotor is directional, so install it according to the indicated rotation direction to optimize performance and longevity.
