I installed new shocks and struts this spring my question is can i still install lowering springs withe shocks i already have?
Yes? No? Whats the question exactly? Are you asking if you can install lowering springs with your new shocks and struts? Or with the old ones? Regardless the answer is yes.
If you get the eibach pro kit (1.5" drop all around) you won't have any problems with stock ride height components, at least I haven't had problems. Any more drop you will likely need cc plates
