I have a set of Impreza struts for 93-01, or 02-07 if you don't mind swapping top hats. the fronts came off my FWD car shortly after i bought it (08 ish) and were supposedly recently replaced. the rears came off a 95 at the sparks Pick n pull. I currently have one on my car and its functional.
(I'm not 100% sure they will work for a wagon, wagons might have a wagon specific top hat or something?)
you could mark your struts and camber bolts, and when you swap back your alignment should be very close to what it was when you took it off.
i think the sparks pick n pull charges $38 per "coil over" , and i think Tim has some stockers with Koni inserts for sale (would probably be great, even with stock springs) my rally car is valved very soft, and I think its great for rallyX
lmk if you're interested on that. they are just "useful junk" to me but i'de love to see someone else get into the sport (esp in a wrx ) wrx = LOTS OF FUN in RX ...
