The best Power Stop Z23 brake kits for a Subaru WRX are the Z23 Evolution Sport kits matched to your generation and axle: front kits for 2002-2003 and 2006-2007 WRX, and rear kits for 2006-2007 and 2008-2014 WRX, with the rear kit also fitting 2009-2013 Forester XT. Each kit in this collection is sold by axle, so check your year and model and confirm front or rear before ordering.
Z23 Evolution Sport kits pair carbon-fiber ceramic pads with drilled and slotted rotors, aimed at daily-driven cars that see spirited use. Because these are complete axle kits rather than pads alone, they suit owners whose rotors are worn or due for replacement at the same time as the pads.
If you only need pads, shop the wider brake pads range instead, and read our guide on whether you really need upgraded brake pads before deciding between pads alone and a full kit.
Power Stop built its name on complete, vehicle-specific brake kits that bundle pads and rotors matched to one application, removing the guesswork of pairing compounds and rotors yourself. The Z23 Evolution Sport line is its street-sport offering, for drivers who want a firmer pedal than tired stock hardware without a track compound.
EBC Brakes is the British brake specialist many WRX owners cross-shop, with pad families that step from street use toward fast-road and track work. Its Redstuff and Yellowstuff names appear throughout our brake range, giving drivers a clear ladder of compounds to compare against the Z23 kits here. EBC is a useful benchmark if low dust or a more aggressive bite is your priority.
Brembo sits at the original-equipment and motorsport end of braking, supplying calipers and systems fitted to performance cars from the factory. Few owners need a full Brembo conversion for street driving, but its catalog parts show what a premium setup looks like. For a bigger step, browse our big brake kits.
Two popular starting points are the Z23 rear kit for 2008-2014 WRX and 2009-2013 Forester XT and the Z23 front kit for 2006-2007 WRX. Match the kit to your chassis years, and replace hardware axle by axle so braking stays balanced side to side.
Are Z23 kits sold for the front and rear separately?
Yes. Each listing covers one axle, so a full refresh means ordering the front and rear kits for your generation. Check your year and model on each title, because the year ranges differ between axles.
Do I need a tune or any supporting mods after fitting a brake kit?
No. Brake kits are a mechanical replacement and need no tune. Bed the pads in following the maker instructions, and bleed the brakes if the system was opened during installation.
How difficult is installation?
Most owners with a jack, stands, and hand tools can fit pads and rotors at home, but brakes are safety-critical. If you are unsure about torque specs or bleeding, have a shop do the work and check the pedal before driving.
Will a Z23 kit fit my Forester XT?
One rear kit here is titled for 2009-2013 Forester XT as well as 2008-2014 WRX. Other kits are WRX-only by title, so check your year and model carefully before ordering.
