Like Hog & Cracker reccomended, locate a coilover spanner wrench. Start by putting the cars chassis (not the suspension) on jackstands. Spray the threaded lower section of the shocks with lubricant. You'll see the two big "collars"(spanner nuts) with notches in them on the bottom of the coil, back off the lower of the two with the spanner tool and then turn the upper collar a few turns keeping track of how many revolutions you make. Do the same for the other side, let the car off the jack and see if the height is where you want it. Once you're happy with the ride height remember to go back and tighten the lower collar back against the upper. Let us know how you made out.
