basically you need to increase your spring rates in the rear or soften them in the front. Sway bars are just a means of increasing your effective spring rates. If you have adjustable shocks setting them on firmer settings are another way of increasing your effective spring rates. You can also play around with tire pressures less pressure in the back will help the back end come around but can cause sudden snap steering if you unload the suspension too quickly (during an avoidance move). Adding more weight to the back of the car also helps as far back as possible or taking weight out of the front.
