Now I am stuck. Called RalliTek and they basically said they do not have a 1/4" lift spring for the 2004 Legacy. Back to square 1 with a disassembled Baja in the garage. Sent questions to King Springs, not confident I'll get a response other than "we don't know" or "we don't make those anymore".
I'm afraid to start researching how to get Impreza springs on a Legacy because who knows what kind of lift or drop I'll end up with. My luck is the springs push an extra inch and my rears are lower than the fronts.
