The $150 under the bodywork camber plates won't really affect the ride comfort normally other than some more road noise into the cabin due to the pillowball mount, however they DO reduce suspension travel by about 3/4" because of the design. Due to this, don't go too low or your bottom out more unless you have shortened struts.
The Ground Control camber caster plates, OTOH, increase travel and adjustability but only work on coilovers and cost $350.
