I have them in mine. Lowers the car about 25mm, so it's quite subtle but a very nice improvement in the look and overall stance of the car. The rear end in particular sits too high as standard IMO.
I have posted before & after pics on here before if you search my old posts!
Ride comfort not really noticeably affected, perhaps on very bad bumpy surfaces it's a little firmer but not too noticeable IMO.
