The best street/handling shock out there is the Koni. They are not cheap. If you want some better handling for spirited driving, maybe a set of swaybars should be in the plan. $379 from Stranoparts for a matched set 35mm hollow front and 21mm rear. Poly/solid LCA's and solid/solid panhard really improve handling aswell.
Unless you are planning on road racing it i'm not sure i'd bother going that far though. Maybe re-bush the tired front end with a poly kit or something. Otherwise I'd just put the blower on and leave it lol.
