I used the Kappasphere lowering springs, and I am very happy with the results. I had them installed yesterday and they also did a 4 wheel alignment. They lowerd the car 1" front and 1.5" rear. It now measures 27 1/4 front and rear. The car looks great and the ride didn't change much. The only thing I have to watch for is road kill as I am sure my spoiler will make a nice plow to clear the road.
