i thought coilovers were named as such because the adjustable sleeve for the coilsprings sits over the shock........? don't get springs.... they're a waste of time. get coilovers, skunk2, and groundcontrol are the better brands. the advantage is that you can have the same spring rate as a coilspring setup (which allows equal weight transfer control), but also have ride height adjustability to improve your acceleration and center of gravity. if you're going to get shocks while you're at it, then save up and get a proper full-coilover suspension like the tein type-ha's
