With the drop you will need the caster/camber adjustment. The Eibach kits has adjustable upper A-arms in front (both adjusts caster and camber), adjustable toe bolts and camber arms in the rear. My settings came back into factory range with these. The kits are not cheap but give you the sense of security. After all the tires are $375 a piece so wearing a set of 4 will cost you more than the kits.
