You DO realize that in order to make the rear 2-pots work you will need a WHOLE LOT more than the calipers, don't you???

It 'aint just an easy swap.

 

If you are serious, then you will be ordering A LOT more than just the calipers. The whole thing will cost ~$1500 in parts, bought new.

For a street car it is a HUGE waste of time, effort, energy, and money to do Subaru 2-pot rears on a WRX, IMHO(and many others).
Most people are real happy with the 'H6' rear swap(cost ~$225 in parts, new), but if you MUST....check ravensblade.com
There is lots of good info there.
Check some of the vendors too, ordering from Subaru may cost more than from a vendor. If you are talking about the rear USDM STi Brembo brakes then be prepared to spend even more to make them fit/work.

 

why do you want the 2 pot so bad....IMO i would just get the wilwood set up for 1500 you can get fronts and rears...

my 2 cents

 

It's not the sharing...its the stupidity.

What part of 'Don't do it' don't ya get?

 

Here's the Japanese part #'s. They should be the same as US if these are available in the US:

Calipers
Right-26692 FA060
Left -26692 FA070

Caliper Parts(pads, pins, rattle clips, etc...)
Same for both sides(need 2)-26696 FA010

Any other questions, just ask.

 

There is also a bracket available so you can retain the R160 diff, hubs, and axels. Then you'd only need to swap the calipers and rotors.

 

I don't see why it's stupid. I'm doing it, and I think it makes sense considering I have Subaru 4 pot fronts, and this is the four wheel brake system used on STi versions 3-6 along with the nifty limited run models like the RB5, P1, S201, and 22b. Furthermore, I'm doing it because my choices are either A) STi gold Brembo rears or B) Subaru 2 pot rears because I am using R180 hubs. I dunno if you've looked at the USDM STi rears yet, but the old school 2 pots seem the wiser choice to me. I don't see why Subaru knew less about what they were doing with the 4/2 pot setup than they do with 'stock' fronts and rears. However, I will say it is silly to do any sort of rotor/caliper upsizing in the rear without significant improvements up front first.

 

If you are not going to race the car it is, IMHO, a waste of money(and everything else) to do the Subaru 2-pot rears. There is VERY little to be gained over the H6 rear conversion, anyway...and IF you are going to race the car, for the same or even LESS $$$, you can get BETTER rear brakes....so doing the 2-pot Subaru rears on the USDM WRX is, IMHO, a STUPID thing to waste time, effort, energy and money on for little or no benifit and the use of non-standard parts makes maintenance a headache as a result as well.....

SO....when the pros and cons are all put out on the table and everything is considered......the Subaru 2-pots in the rear are a waste.

PS...I researched this whole WRX brake bit for almost a year before I came to this conclusion, so it really is an informed conclusion, not just an uninformed opinion.

I have 4-pot fronts w/dba4000 rotors and H6 rears w/dba657 rotors....Bobcat pads in front and Ultimates in the rear(soon to be less grippy pads due to a bit too much rear bias) along with SS lines and Motul 600RBF fluid....

They have the parts you are looking for in the Brakes section of the sport parts.

 

That's the first time I've seen them under $1k.....still too much$$$ though.
