Detailed Product Description

This Dynamite Friction DFC Brake Rotor - Drilled and Slotted - Black is a disc brake rotor designed to meet the specific braking requirements of the Genesis G70 and Kia Stinger. The rotor features a directional surface with both drilled holes and slots, which help to reduce heat buildup and evacuate brake dust and gases during braking. The nominal thickness of 22 mm ensures structural integrity, while the discard thickness of 20 mm indicates when the rotor should be replaced to maintain safe braking performance.

The rotor’s hat is finished with a zinc black coating, providing a rust-resistant barrier that helps prevent corrosion over time. Additionally, the entire rotor surface is treated with a rust-resistant coating, enhancing durability in various driving environments. The 5-bolt hole pattern with a 12.5 mm diameter and 114.3 mm bolt circle diameter ensures compatibility with the specified vehicle models.
