with a mild spring/strut combo, you wont have to worry about bad camber problems unless you go more than 2" lower. and even eibach prokit rated at like 1.5" looks good enough if u have the right wheel and tire combo. id still get it aligned after you pick up all the stuff ur going to swap out (do check bushings and the arms for wear and bends, u might wanna look into doing tie rods/bushings at the same time so u only have to align it once).
