Detailed Product Features and Specifications

This DFC Brake Rotor - Drilled and Slotted - Silver features a solid disc brake rotor construction with a directional surface type combining both drilled holes and slots. The drilled and slotted design helps to reduce brake fade by allowing gases and heat to escape more efficiently during braking. The rotor’s nominal thickness is 11 mm, with a discard thickness of 9.4 mm, ensuring safe replacement intervals. The zinc silver finish on the rotor hat provides additional protection against rust and corrosion, which is critical for maintaining performance over time.

The rotor measures 302 mm in outside diameter and 71.5 mm in overall height, fitting precisely on vehicles with a 5-lug bolt pattern and a bolt circle diameter of 114.3 mm. The 12.5 mm bolt hole diameter and center hole diameter of 69 mm ensure proper alignment and secure mounting. This rotor is designed specifically for Hyundai and Kia models including the Santa Fe, Santa Fe Sport, Santa Fe XL, Sedona, and Sorento, making it a direct replacement part for these vehicles.

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

The DFC Brake Rotor - Drilled and Slotted - Silver line from Dynamite Friction focuses on delivering rotors with enhanced heat dissipation and braking performance through a combination of drilled holes and slots.
