Prokit is perfectly low... H&R Race springs are also a great choice. Idealy, our cars shouldn't be lowered more than 1"-1.5" before you negatively effect handling, ride quality, bumpsteer, etc. The
Eibach dampners (shocks/struts) aren't the best, I would reccomend Tokico HP (blues) if you're on a strict budget, or Bilstein HD shocks/struts if you have a little bit more to spend.
The shocks/struts and spring combination is going to be what really determines the "feel" of the car, but some nickle/dime items can really help make the car feel more solid. I would reccomend picking up a set of maximum motorsports center-drilled aluminum rack bushings and their caster/
camber plates when doing the springs and dampners.
I myself have had both the Eibach ProKit springs with the Tokico blues AND Bilstein HD's I reccomended. The Tokico's road a bit rougher than the HD's, but both performed roughly the same.
If all you're looking to get is shocks/struts/springs and you really want to max out that $1000 you could do MM C/C plates, front/rear coilover kit w/ springs, and bilstein HD's (which can be found considerably cheaper with FREE shipping on ebay).
