if you want to be economical, get regular add-on coilovers which do ride like shit, if you are on a bigger budget get either ground control coilovers with kyb struts or a tein 16-way damper kit, dont worry about how many inches you'll drop, just use your eyes after you get it installed, springs will ride good but I personally dont recommend them because they give you absolutely no adjustability in case you dont like how it looks for one reason
