Eibach Sportlines. They have a 1.8" drop. Pretty nice ride.
You'll only bottom out on bad pot holes or dips. If you don't really have bad roads or you actually pay attention while you're driving, you'll be fine. I've put lowering springs and coilover sleeves on 150k-200k struts before and rode with no issue(except the ebay coils were bouncy as crap...)
