Best way to make a FWD car more oversteer biased?

[Formally...]

I would do the larger rear sway bar and even look at getting a smaller front bar. This will make the turn in of the car a little slower but will allow the front to bite better. Most people think that you want a car to stay as flat as possible through a turn but it depends on the turn and speeds. If you are planning to auto-x the car then I would do the larger rear bar and slightly stiffer spring rate if you have an adjustable shock to match to the spring. In auto-x a slightly tall happy FWD car can out run a RWD and AWD car.

Very true, those ITRs out there are wicked.

and those crazy CRXes... seriously though, an autocross-centric (big rear bar, set up to rotate crazily well) set up like they mentioned *might* not be ideal for a street car or a hpde car, it all comes down what your goal is. However, I'd suggest against getting better tires in the front or more tire in the front BEFORE you try the other, more common solutions.
