Mounting wheels with small Toe-In angle for straight line stability.

In RC cars a small toe-in angle between 0-3 degrees is used to increase straight line stability. How about using the same concept with
differential steering robots, with 2 wheels and a caster? Has anyone tried it?
Here is link which explains Toe, Camber and Caster angles of wheels. http://www.ozebiz.com.au/racetech/theory/align.html
With a Toe-In angle there will be some scrubbing of the wheel and loss of power. Question is how much will it help in keeping the robot going straight with a diff-steering drive system?
