looking into dropping my mazda3 5dr but dont know what to get, iv looked into mazda3online.com (RTM) (just the springs) and well their all good but most of them just say bout handeling and performance, and not much into how much will be dropped, i think just one tells me how much it wll drop. any of you guys know which is a good decent set of springs is good for dropping a mazda3 and that will have good handeling?
