I don't think that's 3 inches. My car sits on the ProKit from Eibach and actually sits about that height if not a little lower.
I'd say your best bet will be to look at the springs and see if they are lowering springs or hacked up stock springs. You can lower the car on the stock springs using a couple different methods if you do it correctly, but few know how or take the time. If they are lowering springs, just get some good shocks/struts. If they are hacked up stockers, I'd reccomend getting new springs (either lowering springs, stock springs, or getting stock springs and cutting them if you want)
and getting shocks/struts, because like I said, they're likely blown.
