Handling is more then shocks and springs, for the best set up, you'll want a rear swaybar, and a front castor kit. if you lower (dampers and springs or coilovers) you should get a adjustable panhard rod too. Do you go on track often? if so, go for coilovers, if not, save the money and stick with shocks+springs, dont really need the castor kit either, but the rear swaybar is desireable. to improve handling,
