I've had both- DMS 40's, now the STi spring/strut setup. Coilovers have the obvious advantage of adjustability- damping (some double adj), ride height, normally several spring rates to choose from. How important that adjustability is dependent on what applications you have planned for your rex and how neccessary those adjustments are. Other advantages of the coilovers are the ability to corner weight your vehicle and that most are rebuildable.Ludachris said:Which do you have? Obviously, coilovers are more expensive, but are they the better choice? Do they offer that much more as far as the ride is concerned? For street use, can a good set of adjustable shocks and stiffer springs do just as well?
