I recommend that you don't attempt to set the 'toe-in' yourself but take it to an alignment shop and ask for a 'toe-in' adjustment. The figure I fall back on is 1/8 inch at the wheel rims. Doing this accurately is impossible without the proper equipment, so for safety's sake, go to an alignment shop.
