I went with H&R Super Sports. They are advertised at 1.7fr and 2.4rear drop but it is not that drastic of a drop. Perfectly level at 1.5 and 2.0. I can tell you not to buy a Hotchkis panhard bar. Yes its adjustable but you have to take everything apart to adjust it, a total pain in the ***. I would replace your shocks/struts, the ride is so much better. You can also do GT500 mounts or reuse your factory mounts, you might get lucky and not hear any noise after awhile.
