I've lowered mine on Eibach springs, I felt that it sat way too high and that it rolled about a bit too much in corners. I was a little concerned that the Eibachs wouldn't give the drop I was after because in some cases they don't but they were pretty much all that were available and they have always given a good ride quality. I was pleased with the results, it now sits much
lower, slightly more on the front now which I like and the handling has improved quite a bit.
I do have pictures but only with the car running on 16" winter steels and not the 17" wheels unfortunately. In short I would definitely recommend the Eibach's.
