I know a lot of you guys have put on lowering kits. I would like to put on the eibach sportline kit but have a few questions. I was thinking the complete kit with springs, shocks and sway bars but it is kind of expensive. Can you put on the springs but use your stock shocks and is the ride o.k.??? If you go with the eibach springs and stock shocks can you still add the sway bars???
