If you want to go back to stock, I would recommend waiting for a full set of stock suspension (shocks and springs) to come up for sale second hand. Its easier and quicker to install cos you dont have to take the struts apart to get the springs out. You can just swap the whole units over. Also, who knows how much life is left in your stock shocks...it would suck to spend $500+ on parts an labour to get it back to stock and find your shocks are near rooted anyway. if you can do the install yourself...different story.

BC coilovers (not buddyclub) are only about $1200 a set and people seem to have good things to say about them considering they are only cheapies.
