Vehicle Fitment

• 2015-2021 Subaru WRX (2.0L Turbo H4, AWD) - without EyeSight Driver Assist Technology; 2-piston front / 1-piston rear calipers

Fitment Notes

• Rear axle kit only - for a complete front and rear Z26 upgrade on this platform, see PowerStop K6932-26
• Fits WRX models WITHOUT EyeSight Technology ONLY - WRX models with EyeSight use a larger rear rotor (11.81 in. / 300mm) and require a different kit

• No special modifications required - direct bolt-on installation

Features

• Z26 Street Warrior Carbon-Fiber Ceramic pad compound engineered for high-horsepower performance cars - delivers brake torque consistently higher than OE with outstanding thermal stability and fade resistance up to 1,500°F
• A meaningful step up from the Z23 under hard repeated braking - purpose-built for the WRX's turbocharged AWD performance character on spirited street drives and occasional track use
• Drilled & slotted solid rear rotors maximize heat dissipation and clear gas and debris from the friction surface
• Low-dust formula validated through on-vehicle third-party testing - cleaner wheels without sacrificing pad bite

Product Description

The PowerStop K6977-26 Z26 Street Warrior Rear Brake Kit is the rear Z26 upgrade for the 2015-2021 Subaru WRX without EyeSight. The Z26 Street Warrior Carbon-Fiber Ceramic pads deliver brake torque consistently higher than OE with thermal stability up to 1,500°F - a step up from the Z23 for drivers who push the WRX hard on the street or on occasional track outings. G3000 iron rotors are precision-cast to OE tolerances for a direct bolt-on fit with no modifications required.

Confirm EyeSight status before ordering - WRX models with EyeSight use a larger rear rotor and require a different kit. Does not fit WRX STI. For a complete front and rear Z26 kit on this platform, see K6932-26. For the Z23 Evolution Sport version of this rear kit, see K6977.
