Before you spend lots of money on suspension mods, have you tried trail braking? You can get the front end pretty planted and rotate the car a bit just by trail braking. Don't get me wrong, there's plenty of room to improve the stock suspension setup, but a few little driving techniques can really bring the handling into check on these cars.
