When any of the wheels loses contact with the road surface, there will be a deviate in handling; each of the suspension system should keep all wheels on the road surface in spite of hard cornering and in change of steering position. It’s always pleasing that that car can be set for a tiny amount of understeer so that it responds predictably to a turn of a steering wheel and the rear wheels to have a smaller dip angle than the front wheels. However this may not be achievable at all times due to the vehicle load, road condition, weather, speed and this consumes excessive time for the driver to adopt.
