Product Line Details: DFC Brake Rotor - Drilled and Slotted - Black

The DFC Brake Rotor - Drilled and Slotted - Black line from Dynamite Friction focuses on rotors that combine drilled holes and slots to improve braking efficiency and rotor cooling. This product line features rotors with a zinc black hat finish for enhanced rust resistance and a directional surface design to maintain optimal brake pad contact. The 633-31130R rotor exemplifies these characteristics, providing reliable performance for vehicles requiring vented rotors with precise fitment.

Technical Specifications and Features

This disc brake rotor has a nominal thickness of 24 mm and a discard thickness of 22.4 mm, ensuring a long service life before replacement is necessary. The rotor measures 345 mm in outside diameter with an overall height of 64.1 mm. It features a 5-bolt hole pattern with a bolt circle diameter of 112 mm and bolt hole diameters of 16.7 mm, matching the stud/lug hole specifications for secure mounting. The rotor’s surface is both drilled and slotted, which helps to evacuate brake dust, gases, and water, improving braking consistency. The vented design further aids in heat dissipation, reducing the risk of brake fade during extended use.

Compatible Vehicles and Applications
