spend the money and get the shocks/struts/cc plates. especially if you're doing the springs the shocks/struts cause you already have the car apart. no need to take it apart twice if you dont have to...save you time.
How low do you want it? Its probably a good time to replace the struts, but if you don't want it super low you can cut your current springs which isn't too bad, I cut a little bit off and I'm happy with it (both ride height and quality)
