Just make sure they are installed correctly. I know this sounds ridiculous but a few months ago a guy came to my shop with some camber caster plates because another shop told him he needed them. Come to find out the other shop installed the camber bolts the wrong way. We just re-installed the camber bolts and set toe. Customer was very happy but unfortunately had to deal with not knowing what to do based on the other shops error and of course ate up some inner tire.
