I've had different toe-ins and outs and so far the car still wanders and feels a bit nervous at some speeds, and is difficult to keep in a straight line.
But rather oddly it does sort of suit the car and perhaps isn't as bad as yours sounds.
I do know the tracking has been changed from time to time so I would speak with a few dealers to see if they have any advice, since they have been trying to different settings to get the best compromise.
