i know you are supposed to upgrade your shocks and struts when you get lowering springs but can i go a few months after getting the springs before upgrading. cuz i wanna go ahead and lower it but i wont have to money for the shocks and struts for a couple months. also, would the h&r super sports made for a 94-04 convertible fit a cobra convertible, is there a difference in fit for springs for a cobra versus a gt.
