Handling improvements Dodge Dart??

Already have the front factory sway bar with new bushings, have found an Addco 3/4 rear sway bar at summiy for a decent price, have KYB Gas Adjust shocks to install, still looking at 14 tires, selection is really limited, entire front end has been rebuilt. I don't want to shell out for aftermarket A frames. What else can I do (within a limited budget) to improve the cars handling characteristics?? The factory sbp ralleye rims are only 5.5 wide and I am hesitant to put a nine inch rear tire on that small a rim.. Your thoughts??
