The ride is firmer all around (which I like, because it feels like there's less slop in every corner or bump), and is only bone-jarring on uneven bridge sections or potholes (which you should avaoid anyway). You will notice that you can't take driveway lips (the ridge where the pavement ends and sidewalk concrete begins) as fast as before. So slow down when you pull into McDonald's or else your steering wheel will snap your wrists when it jerks 45 degrees in one driection. There is slightly increased tramlining and tendency to follow grooves and road irregularities (but this only happens when braking to a stop and all the weight has transferred to the front wheels). I'll easily bear this annoyance for the enhanced steering sensitivity I now enjoy at 60 mph corners.
After doing this upgrade, I started to feel that the car should have had 17" wheels all along. My E34 540i with stock wheel sizes feels so mushy, almost like a Cadillac (gasp!)
