Actually i just noticed that the whiteline guys prob have the best upgrades in this domain. Heres the link to their products, or if you do a search at the bottom of their page for a subaru, impreza, 03-07 turbo wagon itll bring up a list of all the parts that fit my car, which parts do you guys think id need most? Thanx again. Man this is fun
