I have the Eibach Pro kit and, although they seem a hair longer, the car did drop about an inch and a half. Also the stiffness of the ride did not seem to change much at all. The only problem I have is my front camber is a little off leading to excessive wear on the inside of the tire. I've been told that it is an easy fix, adding a spacer, but I'm not a suspension expert so I'm not sure if it will really be that easy.
