I have never tried Eibach and was really un-decided for a while between the two springs available. Eibach's were reported to lower 1" F/R, with a firm feel as most have stated. H&R's lowered 1.3"F/1.2R, were reported to give a better ride quality. I decided on the H&R's for that reason, and at this point I'm satisfied with the look and the ride. Much better than stock, and I thought stock was stiff, but a good feel on the road. But not without an STB. That's another post by itself. But .H&R's I'm sure you'll like
