IMO one of the most cost effective mods for performance is a good set of tires. Instrumented reviewers have demonstrated the gains in lap times etc. Second would be driving lessons (second due to somewhat higher cost and limited availability).

Another plus for going the new shoes route is it keeps your warranty intact.

Also lightweight wheels. You can easily shave 5lbs/corner off the car and it's in the best possible area: un-sprung, large-diameter rotating mass.
