I dunno about the banging when you stop and turn. When I have mine on, it bangs when I just go through dips and bumps, but it does go away and the bang is from hitting the fender. But you also mentioned that you havent put in springs or shocks yet...either when you get your shocks and springs put on (if it's in a couple of days) or soon, ask the mechanics to check if they are okay. You don't want something from you camber kit coming out while you are driving (that's what happend to me)
