if you get wheels and tires from www.wheelsnext.com
they include free springs, dunno how good they are, but it's something to think about. but then again springs are cheap compaired to wheels so you could get them both at the same time if you save a bit more cash. But then there's installation to consider, if you can do it yourself you can save yourself a few hundred bucks if not then maybe get wheels and then springs when you have more cash. I would deffinately get the wheels first as oposed to the springs because then you can figure out based on the wheels and tires and current height off the ground how much of a drop you actually want and then get springs to fit your setup.
