Well the correct thing is to run it as specified by the factory
Toe in helps turn in as the wheel that gets weighted up is then pointing the way you want to go.
Running toe out is an amateur way of trying to increase cornering ability which is quite different to turn in and the degree of toe out than can practically be dialled in is actually completely insignificant to the relative toe out generated under lock.
Steering geometry allows the inside wheel to turn at a stronger angle than the outside wheel as it needs to follow a tighter arc, called ackerman geometry if anyone wants to look it up ie when on lots of lock the front wheels have toe out relative to each other. Simply adding more static toe in and believing it to
help simply suggests that the best automotive engineers in the world couldn't get it right when they designed the car - err no! If a bit more toe out would
help they would have desgned in more ackerman to begin with. There is no downside to ackerman. If the car could use more they would build it with more.
However and whatever, anyone who has a road car wearing tyre insides off will benefit from
a) a bit more toe-in or less toe-out
b) firmer bushing
c) replacing any worn joints
