When my friends put my camber kit in it was also like that , even when I was steering, all the sudden, the back would lose control. I wouldn't drive it at all until you get it to an alignment shop and the nearest one if you can. I left my camber kit alone and let the camber bang out my fenders itself, now the camber doesn't hit unless I go over railroads too fast (when I don't slow down enough) or big bumps and dips.
