Detailed Product Description

The DFC Brake Rotor - Drilled and Slotted - Black from Dynamite Friction is a disc brake rotor designed to meet the braking demands of Hyundai Sonata and Kia K5 vehicles. Its drilled and slotted surface helps to dissipate heat more effectively during braking, reducing the risk of brake fade under heavy use. The directional surface pattern is engineered to channel gases and debris away from the rotor surface, maintaining consistent contact with brake pads.

Constructed with a nominal thickness of 12 mm and a discard thickness of 10 mm, this rotor ensures a balance between longevity and safety. The zinc black hat finish and rust resistant coating provide protection against corrosion, extending the rotor’s service life. The rotor features five bolt holes with a diameter of 12.6 mm and a bolt circle diameter of 114.3 mm, matching the factory specifications for the compatible vehicles.

DFC Brake Rotor - Drilled and Slotted - Black Product Line

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction focuses on rotors that combine drilled holes and slots to improve braking efficiency and heat management. This product line is designed for drivers who require rotors that maintain performance under demanding conditions, such as frequent stop-and-go driving or spirited driving on Hyundai and Kia models.
