As ^^ You will feel the road/bumps a little bit more, but the car feels them a lot less (if that makes sense) You'll know if you go over some corrugations etc, but the car will act as if they weren't there. It's not really any less comfortable than the OEM, just a little different. You'll notice a lot more, but not in a jarring way. That's at cruising/commuting speed and conditions. As soon as you give them a bit of load or weight they immediately become so, so much more comfortable than the OEM's. A bit of throttle and the road just seems to smooth out and corners seem to increase in radius
