I replyed to this once but just to say whats been said by others. Only by true coilover setups. And as posted above Dropzone coilovers suck. I have dropzone springs and agx adjustables and I will say that for me, it rides smooth rough if you hit a big dip but not as bad as people make it sound. Also tires play a big factor in how your car is going to ride. I have about an inch and a half of tire on my 18s so that makes a huge difference in quality if you have 16s you are basically good with any type of strut made for our cars. You don't need a big expensive setup to have a good ride quality.
