Lowering springs are typically a tad stiffer and shorter. Giving you a lower center of gravity, and firmer ride. If not designed right, when improperly matched to the dampers, you'll have a bouncy ride.
KW allows for tuning this oscillation out both on compression and rebound, as well as fine tuning ride height. At a cost of course. But its a properly designed "turn key," solution.
