I always try to speak to the person who is buy if possible. I like to do more of a specific catering to the individual. Ask what are their goals for the car? What will they be using the car for? I also like to go over the pro and con's of the upgrades they are purchasing.
From what i understand your looking for a slight upgrade to the stock performance. Something very street-able but good fun on the on ramps. I would start out with Sway bars and some springs. If that just isn't enough then i would get a set of bushings. That will tighten it up a bit more. If your going to hit the track every now and then , trailing arms and toe links would be next.
Thats just a quick response. Fell free to pm me or call me to go over pricing or more specifics of what you could do.
