if you want some monster over steer you can get dampening adjustable shocks and set the rear to max stiffness, get a stiffer rear swaybar, rear strut bar, and have zero or some positive camber.
but i don't think you want oversteer on FWD because its going to make your car extremely slow when trying to take hard corners. not to mention it can be super dangerous if you don't know how to recover.
