Well i just installed the H&R sport series srpings not only a week or so ago. They dropped me about 2" in the front, and about 1.6 or so in the rear. NO noises, ride is excellent, and the rear still sits slightly higer with a heavy speaker box in the back, and a full tank of gas. I'm on stock struts too by the way. Got the springs at tirerack.com for 211 bucks. Just look at my signature pic to give you an idea of the drop. Also check out the interior/exterior forum for my post of my new wheels and drop. The reason i chose the H&R's was for exactly the problem you have. It seems like Eibach didn't take into account the added weight of a system or full tank of gas to keep the rear at the same level or higher than the front. I'm very happy with the H&R's.
