Or howabout 6WD...Even more maneuverable than 4WD, i think i spelld that wrong. Oh well. Because the turning radius would be around which ever side has the more weight because the middle wheel is slightly lowered. This may add some more weight though, but you could just have two gearboxes, one for each side, and then have the gearbox placed in the middle of the robot and attach the middle wheel to that and use two sprockets, one for the front and the other for the back. That's a basic 6WD drivetrain. If you're using the gearboxes from the KOP, you are going to have to machine wheel hubs because the wheels they provide do not fit onto the shaft. Also you may have to purchase new sprockets to fit onto the shaft coming out of the gearbox because I don't believe that the two sprockets including the wheel can all fit on the gearbox. I dunno, that's just what I gotta say. Good luck on your robot.
