I got the powerstop remanufactured brembo 4pot/2pot for a 2008-2017 STI on my 2018 WRX I found online for less than $800 with pads, calipers (red powder coated) and drilled and slotted rotors.
I also do highly recommended the power stop brand calipers...And their customer service is excellent. I had a problem with one...They sent me a new one anyway. They do stand behind their products.

I recently got a set of reman'd Girling calipers off RockAuto -- they fit perfectly.
In the early aughts I scored a set of the Girling 54 calipers from a 16v and my dad and I rebuilt and painted them before installing in my first '84. I didn't upgrade the MC (didn't know better at the time) so the brake pedal travel increased but the braking improved so I kept the set up ... until the next annual MO state vehicle inspection where the car failed for excessive brake pedal travel The 9.4" set up went back on.
There’s two lines, as the caliper is split into two sections vertically. The top two pistons (inside and outside piston, directly across from eachother) are hooked up to one brake line, and the other line hooks up to the bottom chamber and bottom two pistons. If one brake line fails, you still have some brake pressure (the pair of pistons on the non broken line). Unfortunately, this means that only a pair of the 4 pistons will work with just one brake line (all abs cars). This would make your pads wear at a severe angle, and drastically impact your breaking performance. I’d definitely say just find some rebuild kits for your current calipers. It’s pretty easy and cheap.
I've recently upgraded to Girlng 60 calipers and feel a bit uneasy about the pad to rotor size difference. The discs on your car are 280mm. The Audi discs that the Girling 60 caliper came off of are 276mm but slightly thicker.
I bought new Power Stop calipers. I have not been able to get the brakes fully bled since then. The pedal was really bad. Even after multiple bleeding attempts, including by a shop, it's not perfect. My power bleeder also couldn't seal with these calipers.
Power stop reman parts are trash. Only buy them if you’re planning on re-rebuilding them yourself with oem parts. Out of the multiple sets of calipers, all of them had issues like seals not fitting or being torn up, blasting media left inside the caliper or slide pins, pistons being scored or rusted, etc. The red powder coat was decent though lol.
Be careful Powerstop calipers are just remanned calipers. Poorly powered coated. Paint came off the first winter and one caliper seized up in under a year.
