I'm trying to figure out which valve I need and the information currently floating around the web is sketchy at best. I have an '02 Forester with rear drums and ABS. I bought a 2.5RS rear end and some Legacy GT calipers and rotors. Some people say I need a proportioning valve from a WRX, some say it has to be from a Forester, others say it has to be from a Legacy GT. In addition to the model, I also need to know whether the proportioning valve needs to be from an ABS model or not.
I noticed several people referring to both the master cylinder and the ABS pump as the proportioning valve, which is probably why good information has been so hard to find. I am talking about the actual proportioning valve that sits on the passenger side front strut tower, and controls brake fluid pressure between the front and rear axles.

I could but I'm trying to avoid replacing the hard lines as I do not have the tools to bend new lines and having a shop do it would be expensive. I'm looking for a stock proportioning valve that will bolt up to the existing hard lines.

I wouldn't mind having an adjustable valve but it seems like a lot more work. Have you done it before? I have no experience bending brake lines but it seems like between the tool, the materials, and the labor involved it is a big investment compared to just swapping in the proper stock valve. Especially since I would likely mess up on my first attempt and would end up doing the job twice. If it's not as difficult as I'm thinking maybe I will go that route.

I just did a little searching for a manual valve, there are so many different sizes and options I have no idea where to begin. Wilwood makes 7 different valves.
