All STI Knuckles and Brakes

[67 Car Guy]

I started off with the decision that I needed to use the beefy 27 spline spindle from a 2004 JDM STI. When I couldn't locate any, I decided to break down and go with 2006 STI rear knuckles with the 27 spline axles and 5x114 wheels. Then I started thinking why not go full STI. So I went with the front STI knuckles and the 5x114 hubs, and I figured I'd go with the stock STI brakes all around. Worked out fine in the front. I easily modified the FFR upright adaptors, and I added 1/8" plates to each side to beef them up. I got stock STI rotors for about $25 and a very nice pair of rebuilt calipers for $368 from Rock Auto.

So now I'm trying to order the rear brakes. Got the rotors, no problem from Rock Auto. I go to order the calipers and all of a sudden, I have a problem. Out of stock at Rock Auto. Also out of stock at Autozone, Summit, 1A auto, Carparts.com, partsgeek.com, NAPA, Advance Auto, O'Reilly, Ebay, even Amazon. Nobody has them. I checked with my local dealer. The Subaru P/N's are 26692FE002 and 26692FE012 for the right and left calipers. I'm told they're Brembo calipers. I can order them for around $700 EACH. I went to the Brembo website, and for some reason, they don't list the STI brakes, nor do they cross to the Subaru P/N. They cross to similar Subaru P/N's, which look to be WRX parts. The rep at Summit called Powerstop, and Powerstop finally admitted they don't have any, and couldn't say if or when they might get any.

So, anyone know of a source of reasonably priced rear 2006 STI calipers? (either used or rebuilt)

OR, does anyone know what changed on the 2008 STI calipers? I hear they are similar but different.... I can get 2008 calipers.

Last time I needed something like that, I went to my local auto parts store and bought refurbished units and forfeited the core charge. Time is money and I had my parts right away.

Yeah, that's exactly what I was expecting to do. That's how I got my front calipers. For some reason, it doesn't seem like an option for the rears. I thought maybe I just had to order them and wait a few weeks, but that doesn't seem like an option with Summit or any of my local places. They are telling me they can't take an order. VERY frustrating...

There are a few STI rear calipers on ebay that should work for your application:

At those prices, I’d look at StopTech or Wilwood upgrade.

Great! I searched EBAY but I think I searched for Subaru STI, looks like whats available are the JDM parts. Yes, from everything I've heard they should be a perfect fit.

[67 Car Guy]

I hadn't searched Stoptech. I just checked and..... Front calipers only. Nothing available for the rear. Checked Wilwood again: Nothing for the rear either. Wilwood has a kit for the 818, but it's for the standard WRX hubs (5 x 100). I could probably put something together with a different rotor, but it's still pretty dear ($1562 for the rear).

I think it's going to be Ebay, and then a rebuild kit from Rock Auto....

I had not tried that site, thanks for the reference! I just checked, it's an excellent place to shop for used car parts, and they do have a fair number of options. I've got it saved now for future reference. I've got a pair coming from Ebay, got the pair for $600 including shipping. That just seems to be the going price, when you can find them....
