Product Description

The Torque Solution TS-SU-318.2 Rear Brake Caliper Adapter is engineered for performance enthusiasts looking to upgrade the rear braking setup on select Subaru and Toyota/Scion platforms. This adapter kit allows installation of robust 2004-2007 Gold STI Brembo 2-piston rear calipers onto later model vehicles, significantly boosting stopping power and pedal feel versus stock single-piston rear brakes.

Constructed from precision CNC-machined billet aluminum with a durable black anodized finish, the TS-SU-318.2 is built to withstand demanding street and track use while maintaining corrosion resistance and style. The direct-fit design includes all necessary mounting hardware for a straightforward installation. This adapter requires the use of appropriate 2008+ STI rotors drilled to a 5x100 bolt pattern or compatible aftermarket alternatives, ensuring proper alignment and brake performance.

Ideal for WRX, Impreza, Forester, Legacy, BRZ, FR-S, and Toyota 86 owners seeking enhanced rear brake performance without extensive fabrication, this kit brings larger 2-piston calipers to platforms that originally came with smaller units. Verify rotor compatibility before purchase.
