upgrading

Im planning on doing this upgrade this winter as well.
My problem is i had 2 wheel bearings go out on the rear.
Me & my uncle started tearing it apart to find that everything is rusted to hell.
The rotors, calipers, hub, all the bolts & the backing plate. So im going to replace everything and upgrade my brakes at the same time.
Can anyone tell me if i buy the 4/2 pot upgrade for the front & rear, should i buy 00' hubs or do i need the 06/07 hubs for the front & rear.
And i would also like to upgrade my pads and rotors when doing this install.
I was thinking a slotted & drilled rotor with maybe some hawk pads. Can anyone point me in the right direction to a website where i can purchase pads & rotors that will fit with the 4/2 pot upgrade.

Thanks in advance

Bring this up from the dead. Sorry if i have missed some infos here. I recently just bought 4/2 pots. It just came with pads and calipers only. I searched but for some reasons i still have questions:

1. Front rotors were the same from 02-07 (if im not mistaken), so i bought centric rotors with part #120.47018 along with stoptech ss line with part #950.47004. The front pretty much plug and play. Were they the right part for the front one?

2. For the rears, which part # the rear backing plates. I checked with subarugenuineparts.com and i put 07 wrx tr. they gave me different part #s which was 26255AA061/71 than 26704FE080/90. Which one should i get?

3. For wheel bearing, should i get the 06/07 wheel bearings? Or my stock gc8 wheel bearing. I am using my stock gc8 hubs and knuckles.

4. Are Centrics with part #120.47025 correct?

5. Rear stoptech lines with part #950.47501 also correct?

Thanks in advance for any help

Just an update, You shouldn't have to shave down the kartboy adapters like you used to in the past. I installed mine a few months ago, and didn't have to. However, you still need to add a washer to the bolts it gives you, or else they will scrape the rotor in the rear.

Anyone having done this, did the parking brake parts from the old setup install directly into the backing plate of the 06 WRX or do I have to order a whole 06 WRX parking brake setup?

Hey everyone, my roaring rear wheel bearing tells me it's high time I replaced them and upgraded my brakes in the process. It's time to go to 4/2 pots all around and I'll be using '06 WRX parts. Here is my list so far. I figured I would post this up with P/N's so anyone who wants to do this swap using used or new OE hardware could do so, and to check what I've missed. You can find used calipers on NASIOC or buy them from subaruwrxparts or subarugenuineparts.com, but in case you've missed something, here's the list I have. If I've forgotten anything, please add.

06/07 Rear Wheel Bearings (2) - P/N 28016AA020

06/07 Rear Backing Plates (1RH/1LH) - P/N 26704FE080/090
(you don't need these two if you use Kartboy or poleboy90's adapter brackets)

06/07 Rear 2-Piston Calipers (1RH/1LH) - P/N 26692FE040/050

06/07 Rear Brake Rotors (2) - P/N 26700AE081

06/07 Front 4-Piston Calipers (1RH/1LH) - P/N 26292FE041/051

06/07 Front Brake Rotors (2) - 26300AE061

You can reuse the stock 170mm parking brake. The 06/07 WRX used the same size as the RS and many other Subarus, including '02-'05 Impreza and WRX models. They fit between the rear backing plates and rotors. Just make sure if you get used parts you don't get rotors that fit the 190mm parking brakes that come on STi models with the R180 rear diff. Some older JDM STi models had the same non-Brembo 2-pot rear calipers with a 290mm rear rotor that fit the 190mm parking brake. The stock US rotors will fit even if you have JDM calipers.

As requested, here are some additional small details concerning the pins, clips, shims and springs required. The 4/2-pot calipers have a more complex pad mounting design that requires lots of hardware.

These two items do NOT come in a set of stock pads, and thus need to be purchased separately:
Front brake pins = 26228FA001 (need 4 total, 2 per 4-pot)
Front cross springs = 26232FA020 (need 2, 1 per 4-pot)
(Yes, I know it doesn't look like the cross spring number matches in the picture, but trust me, that's the correct number.)

The following stuff comes in a set of stock front brake pads (p/n 26296FE070), but if you need the individual numbers, here you go:
Pad clips = 26232FA010 (x4, 2 per caliper)
Shims = [26233AE020, 26233AE010 (x2) and 26233AE050] (2 sets of 4 per caliper)
Pad pin brackets = (26244FA010, 26244FA000) (2 sets of 2 per caliper)

I just bought stock pads and Hawk HP+ pads. That way I can drive around on the street on the stockers and go to the more aggressive Hawks for auto-x, reusing the stock shims, clips and brackets that came with the stock pads.

The 2-pot rears are a different design. In this case, a set of stock pads (p/n 26296FE070) came with everything I needed, which was just pad pins, shims, clips and guide plates.

Rear pins = 26628FA000 (x4, 2 per caliper)
Rear shims = (26633FA000 [x2], 26633FA010 [x2]) (2 sets of 4)
Rear clips = 26632FA000 (x4, 2 per caliper)
Rear guide plates = 26632FA021 (x4, 2 per caliper)

:burnout:

What is the rear 2 pot brake pads P/N? The one you listed was a repeat of a 4 pot brake pads.
Thanks!
