Better yet is to go to a 6 (or 8) wheel drop center configuration. This essentially turns a single long configuration into a number of wide ones.

While that is conventional wisdom the actual physics are that it turns it into a situation were two wheels have a high normal force while the other two have a very low normal force. Note the assumption behind that is that the center of gravity is near the center wheels and not close to one of the end sets of wheels.
