I want to know if anyone has used either "sprint performance" lowering springs which give a 2" drop or "suspension techniques" springs which give a 1.6" drop. They are for my stock 2005 lx. Are any other mods required to fit either set of springs? Does the car need to be realigned after installasion? How much trouble to install? I have access to either kit for $130.00. Thanks, Don.
