To install/remove the front springs, you need to pull the wheels, then pull the calipers off of the rotors (hang them from the frame rail hole just to the right of the a-frame mount with a piece of wire or coathanger). Then undo the sway-bar mount from the lower A arm, as this will limit the amount the lower A arm can swing down once the upper balljoint is removed. You must remove the UPPER balljoint from it's seat, not the lower (trust me =P ). Leave a hydraulic jack under the lower A arm when you undo the upper balljoint. Make sure you put the front end of the car into the sky to make sure your lower A-arm has enough room to swing down. Slowly let the hydraulic jack down until it has reached it's maximum travel and pry the spring out with either a crowbar or a metal rod (make sure there isn't alot of tension on the spring still, Shake it with your hand and make sure). After that, just reverse the process on install =) Lowered springs go in a hell of alot easier than the stock ones. As for hte rear, just undo the shock mounts and upper control arms and let the rearend swing down with a hydraulic jack. Those springs just fall out like nothing once you do that. Good Luck, Email me if you have any more questions. And those donuts that you have go on the upper side of the springs, they're for noise dampening.
