WRX STI (2008-17)

Girodisc Subaru WRX STI Rear Rotors Designed for enthusiasts who demand faster response and greater stopping consistency, Girodisc rear rotors for the 2008–2017 Subaru WRX STI combine lightweight performance with race-proven cooling technology. These two-piece floating rotors deliver improved balance, heat control, and durability—ideal for both spirited street driving and track days. Vehicle Fitment Subaru WRX STI (2008–2017)Compatible with OEM Brembo rear calipers and factory parking brake system. Lightweight, High-Performance Design The Girodisc system bolts directly to factory hubs. Some OEM and aftermarket brake pads require minor modification to clear the hardware while retaining the stock parking brake. This simple adjustment involves slightly grinding the backing plate to match the pad’s arc, and full instructions are included. Pads supplied by Girodisc for this application are already CNC-modified for a direct fit. Each rotor assembly combines a 6061-T6 aluminum hat with Girodisc’s proprietary cast-iron friction ring, cast and machined in the USA. The curved internal vane structure acts as a centrifugal pump, pulling air through the rotor to maximize cooling and reduce fade. At only 11 lbs each versus 18 lbs stock, these rotors significantly reduce unsprung and rotational weight for sharper handling and quicker acceleration. Features • Direct replacement for OEM rotors – minor pad modification may be required• 6061-T6 billet aluminum hats, hard-anodized for corrosion resistance• Proprietary cast-iron friction rings cast and machined in the USA• Floating mount system with cadmium-plated steel drive pins• Anti-noise spring washers prevent rattle while maintaining float• Curved vane design enhances airflow and cooling• 11 lbs per rotor vs. 18 lbs OEM – reduces unsprung mass by 7 lbs each• Fully rebuildable – replace only the iron rings when worn• Sold/priced per pair Girodisc A2-095 Rear Rotor FAQs: Do these rotors require modification to install? The rotors themselves bolt directly on. However, some brake pads require minor backing plate modification to clear the hardware. Full instructions are provided, and Girodisc pads are pre-machined for plug-and-play use. Will these rotors retain my factory parking brake? Yes. Girodisc specifically designed this setup to keep full functionality of the OEM parking brake system. How much weight savings can I expect? Each Girodisc rotor is approximately 7 lbs lighter than stock, reducing rotational inertia and improving suspension response. Are these suitable for track days or street use? Absolutely. These rotors are engineered for both daily driving and high-performance conditions, providing better cooling and fade resistance under load. Upgrade your Subaru WRX STI with Girodisc rear rotors for lighter, cooler, and more consistent braking performance—precision-built to handle everything from mountain roads to race circuits.

Girodisc Subaru WRX STI (2004–2017) Front Rotors The Girodisc system is a direct replacement for the OEM front rotors on the 2004–2017 Subaru WRX STI.
