anyone using non-stock specs that they are really happy with?

my 2004 service manual recommends 1mm front toe-in, and 2mm rear toe-in for 18" wheels. Thoughts on this?

My current setup has a tendency to "dart" left and right on the road, and it makes the car very uncomfortable to drive for long periods of time. I suspect it has some amount of toe-out, which I would like to correct.
