In theory, if ya toe the front wheels"OUT" it'll turn better but may wander a little in a straight line. If ya toe the fronts "IN" it'll be more stable at high speed, but not turn as well.. As said above, most run some toe OUT in the fronts.. If it's already toed out a little, just use the trim until it drives straight, that should put equal amounts of toe on each wheel.. Most also run a little toe "IN" on the rears..
