If there is no drop center you will run into scrubbing (robot hopping from the outer wheels having too much traction to allow smooth turning). I have seen the use of Omni wheels to resolve this on a non dropped WCD.
1/8" drop is the norm for the center wheels. If you keep the weight centered well enough, spinning around is very easy! As mentioned, even when weight is not centered, on a drop center drive the robot will rock to one end and essentially be 4wd with a short wheelbase, which will turn much easier with less scrubbing than 6wd non drop..
Yeah robot doughnuts!
