Description

Restore and enhance your Subaru WRX STI’s braking performance with GiroDisc’s precision-engineered 2-piece rotors and replacement rings, designed exclusively for 2004–2017 STI models. Each rotor features a lightweight CNC-machined 6061-T6 aluminum hat anodized for corrosion resistance, paired with GiroDisc’s proprietary high-carbon cast iron rotor rings that excel at heat dissipation and fade resistance.

The floating mount design uses cadmium-plated alloy steel drive pins and anti-noise spring washers, allowing the rotor to expand under heat and self-center between pads while eliminating rattle and noise for smooth, street-friendly operation. These rotors are a direct bolt-on replacement for your OEM parts and maintain factory ABS and brake bias without modification, though some minor pad backing plate adjustments may be needed for rear rotors to ensure proper fitment.

Replacement rings are sold separately for front and rear rotors, allowing you to save money by reusing your GiroDisc aluminum hats when rings wear out. Each set includes mounting hardware for easy installation.

Whether you’re daily driving, canyon carving, or track racing, GiroDisc rotors and rings deliver the performance, durability, and reliability your WRX STI demands.
