What size tires/lift are you running? When you lift a vehicle it does tend to become more top heavy unless you widen your wheel base. That's why prerunner desert trucks that race in the Baja 500 & 1000 have such wide front stances for better stability, grip, etc. The wider the tire, the more contact the tire will make with the ground, offering better grip and handling. Your gas mileage will suffer from the larger tire size but it may be what you are looking for performance wise.
