If you just want to get rid of a little body roll, maybe you should get better swaybars instead. they don't really make lowering springs that only lower the car 0.5" Koni shocks have adjustable spring perches, so you could lower the car a little using stock springs, but Koni's are far from cheap.

If you don't mind going a little lower eibach pro-kit lowers the car about 1.5" and improves handling a bit. With any springs you'd definitely want some decent shocks. KYB AGX is a decent budget shock. If you regularly rotated your tires, you could get away with this drop without a camber kit.
