doesnt matter, any drop changes the angle of the control arms, hubs, everything putting pressure on different points and changes factory specs resulting in reduced tire life and abnormal wear patterns. its up to you if you are willing to replace your tires sooner than you could have if you decide to not use the camber kit. toe is left to right(in and out horizontally), camber is top angle to bottom angle(vertically). when you get an alignment, they will do both and get them as close to stock specs as possible.
