I wouln't change anything with wheels. Try removing bushings and having more adjustable geometry. That will change a lot!
I was shocked what was difference between standard Impreza Turbo and one with heavily altered geometry for rally use and still standard apart from that. It's couple of seconds per kilometer of stage!
