depends on what kind of a drop..if its just for street use then I would suggest some springs..for example some teins give you about a 1.8 drop all around..those with some aftermarket shocks would be a nice combo(either adjustable(kyb AGX's/ Illuminas) or some non-adjustables like gr-2's or koni reds..other than the actual lowering componens your going to need your basic tool set... o, and a breaker bar..I suggest looking into the different types of springs that are out there and their spring rates.. good luck
some other brand of springs are eibach(pro-kit 1" drop and sportline 1.6 drop), goldline springs(either 1.25 or 2 inch srop), H&R, Progress, skunk2.. I cant remember the drops for the last ones...again just do some research..
