Rear sway should be a good place to start, then. Don't go too large or you run the risk of having issues with oversteer. Too small and it isn't doing you much good. You might want to look at a full set of sways and endlinks (for front and back). After that save some money and maybe coilovers? Maybe springs and struts/shocks? IDK, someone will chime in, surely...i got the barenaked base model, dont want to touch the engine ,but i need your advice to improve the handling, on a budget. By the way, don't have[ftp][/ftp] rear swaybars.
