Detailed Product Description

This Dynamite Friction DFC Brake Rotor - Drilled and Slotted - Black is a vented disc brake rotor specifically designed for Subaru WRX and WRX STI vehicles. The rotor’s 326 mm outside diameter and 20 mm nominal thickness provide a solid braking surface, while the 18 mm discard thickness indicates when replacement is necessary to maintain safety and performance. The rotor features a directional surface with both drilled holes and slots, which help to reduce brake fade by allowing heat and gases to escape more efficiently during heavy braking.

The rotor’s hat is finished in zinc black, providing corrosion resistance and durability, complemented by an overall rust-resistant coating to extend the rotor’s service life. The five bolt holes, each 12.8 mm in diameter, fit the Subaru’s 114.3 mm bolt circle diameter, ensuring proper fitment and secure installation. The vented design improves airflow through the rotor, aiding in heat dissipation and maintaining consistent braking performance under demanding conditions.
