I went ahead and put the 05 STI full struts on front and back. I had to modify the front struts because the lower bolt pattern was different and I had to re-drill the holes for the top mounts of the rear struts. Besides that they fit ok.
I've read a lot of posts that say I can't use 05 sti springs/struts on my 92 turbo but I haven't found out why? Any information would help. My friend has stock 05 sti springs that I could get for cheap and I am ok with doing modifications. My 92 is for rally only so I am cool with hacking it up.
