The ride is really good. The general poise of the car is better and the car still takes bumps pretty well. The ride height change has not only dramatically changed the appearance but it has also made you feel in the right position when in the drivers seat. I'd say overall the car now feels like its somewhere between 'comfort' and 'sport' setting all the time. Hitting 'sport mode' still affects the ride as well as the engine response.
