A TechnoKat robot from a few years ago used a pneumatic "puck" that lifted the front end of the robot when the joysticks were calling for a turn. This was on a tank-tread drivebase rather than a four-wheel drive, but the idea works either way.
If you aren't dead set on the supplied wheels, you have many options, including omniwheels. The 2004 KatsKlaw just used
extremely grippy rear tires and enough motor power to make the front wheels slip without too much skipping.
