searched High and Low for this answer...I was looking at suspensions parts and so far there is nothing for 2.5i but is for wrx...they should work i would think.. any one have a clear answer to this?
Sedan or hatch? It made a difference with the GD/GG. I'm not sure about the new chassis. The only part from what you listed that I'd do your research on is the front sway and front endlinks. I put WRX strut braces and rear sway/endlinks on my 02 GG and they worked fine. I had to get a specific front sway and endlinks for the N/A wagon. I had to be careful too, because some sites listed the WRX parts as being a proper fit. So, I don't have an answer for you, sorry, but I can tell you to do your research.
If they're anything like the earlier chassis, the front crossmember will be different due to the exhaust routing on an N/A vs FI. The rears should swap across. I'd shoot Driftin240 or Subytek an email, they spend plenty of time underneath them and can give you a good idea. Erik or Brian (AWDImprezaL or Bielke55) may be able to tell you from the parts manuals as well.
What more info does he need to give? He's got his car right in the sig, and he's extremely clear about what he wants.
Oops. So he does. Then, since it is a hatch, the parts may be different than the sedan even. I'm not sure if the front track differs between the sedan and hatch on the new model as it did with the GD/GG.
I don't think they're different sedan vs hatch, but I could be wrong. I never got to get that much firsthand experience with the 08s, I got canned before I could really crawl around them. I'd say Subytek or Ninjaplease! may be the guys to see on this one.
