You do not want a bigger front bar on a FWD car. You want the vast majority of your sway control to be on the non driven (in our case the rear) axle. Otherwise, the inside tire on the driven axle will have less pressure, thus less traction, and you will have less ability to bring the power on while exiting a turn.
As JohnC recommended, get some seat time, talk to some people about what mods they have made and with what result, and then start making changes to your car. In Dallas, there is a 5 year old honda civic that consistently kicks my butt and the butt of many cars that I consider faster than the contour. The moral of the story, there is more improvement to be made in your driving than in your car.
