I set my Scirocco conversion up by using a set of slide plates. They're mounted on bearings that allow them to only move laterally and the amount they move as the vehicle rolls over indicates the toe under load more accurately than the normal method. I'd set up for a small amount of toe-out, so that the wheels are at zero toe under cruise load.
