there seems to be a debate about the springs, but the struts will add 2" regardless of what spring you use. except lowering springs.
i just put 01 outback struts and springs on my 00 lego wagon. when i compared the strut/ spring setup, lego to outback, the spring height was EXACTLY the same for the front. this suggest to me that the spring makes no difference. and although the piston may be able to compress a little farther, it cannot extend any farther. the extra lenght is in the lower half of the strut.
the finished spring lenght on the rears appeared to be about 1/4 inch taller. the struts were about 2" taller.
so in my opinion, all of the lift is accomplished because of the longer lower half of the struts.
there is a different part number for the lego spring and the outback spring, but even if the outback spring is taller, it just means it ends up being ''stiffer'' because it is being bolted into a mount that compresses it to the lego lenght.
so if you are on a budget, buy used strut and spring setup from a salvage yard, about $40 - $50 each.
if you have the money, buy new KYB_GR2 outback struts and use your lego springs, about 85$ each.
or if you want, buy new or used outback springs and use them with the KYBs. $$??
all 3 will lift the car about 2 inches.
