A good set of springs + lowering usually $500 and above (depending on the brand of spring you pick)

That or get some adjustable coilovers that will allow your to lower/raise your car whenever you like.

+1 for HSD's will be getting a set come time end of year. :thumbsup:

Keep in mind if you were to just add springs, do so if the shocks are in good condition, if they're shagged, lowered springs will not help the handling department.
