Most sport suspensions are like that, at least the good ones!
whenever ppl sit in my car, the first thing they say is "it feels smooth" but yet its still bumpy.....i guess its the preciseness of the suspension that ppl love and the hwy drive makes up for any of the small bump issues....hwy drive feels like you sittin in a plane, lol! OH did i mention i am also running 22's and i still have a smooth ride.

---Tires do have a big part on the performance of the ride, so check pressure monthly to stay safe!
