Subaru Four-Pot/Two-Pot Full Brake Upgrade 2015-2021 WRX

Upgrade your flimsy sliding WRX brake calipers to the better Subaru four-pot front/two-pot rear fixed calipers with this kit. The full kit includes RED (not black like some other vendors sell) four-piston calipers and matching rotors for the front, two-piston calipers and matching rotors for the rear, Centric Posi Quiet brake pads all around, and caliper mounting brackets for the rear.

Note that you are going to a SMALLER front rotor (295mm compared to 316mm on the 2015-2021 WRX) compared to stock. This can be useful if you want to downsize to smaller wheels for rally or other high-performance use. (Many 15″ rally wheels will fit over these brakes.)

Full kit includes front and rear calipers, rear caliper mounting brackets, front and rear DBA brake rotors, and front and rear Brembo pads. Rotor appearance may differ slightly from the photos, but they will match front-to-rear. Replacement pads are 2006-2007 WRX-fit pads.

Note that the front calipers are made of steel, while the rear are aluminum. That might explain why the red color of the calipers are slightly different front to back. That’s just the way it is; please don’t call complaining that the calipers don’t perfectly match. We promise that once they are on the car, most people won’t be able to tell. 

Install Instructions

Fits all 2015-2021 Subaru WRX WITHOUT electronic parking brake. Does NOT work on electronic-parking-brake-equipped cars, since the rear caliper has an integrated electronic parking brake.
