When you lower the car, especially 2+", the camber to the tires will change. They WILL angle in ( something like: / \ ), like mine. That is why you have to buy Camber Links (Hotchkis) to correct it. And with the comment to the car being lifted and the wheels angling out, that is also normal, once the car is lowered, the tires should return to normal. Unless the movement U R talking about is shaking, if so, U R screwed.
