Detailed Product Description

This DFC Brake Rotor - Drilled and Slotted - Silver is a vented disc brake rotor designed to improve braking efficiency by promoting better heat dissipation. The rotor features a drilled and slotted surface that helps reduce brake fade and maintain consistent stopping power under demanding conditions. The rotor’s nominal thickness is 22 mm, with a discard thickness of 20 mm, ensuring a clear service life indicator for replacement. The rotor measures 280 mm in outside diameter and 49.1 mm in height, fitting precisely on vehicles requiring a 5-lug bolt pattern with a 114.3 mm bolt circle diameter.

The rotor’s hat is finished with a zinc silver coating to resist rust and corrosion, while the disc surface remains plain to maintain optimal friction characteristics. The directional design of the drilled and slotted surface is intended to channel gases and debris away from the contact area, improving braking response and rotor longevity.

DFC Brake Rotor - Drilled and Slotted - Silver Product Line

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots with vented construction.
