Yes, if you have a dummy weight to put in the car as the algnment is being done , that could help the outcome.
1/8 inch is standard on a lot of vehicles. Many newer vehicles, maybe not. More like .100 of an inch.
As the car goes down the road , suspension loads, and toe in changes slightly.The tire will tend to fold back, or apart in the front, which is why a little toe in is generally required, or desired. 1/8 of an inch is only 1/16 difference from front to back through the center verticle axis of the wheel/tire. almost negligible.Unless you factor a little for suspension "loading". That tends to zero the small amount of toe.
Fact is stranger than Fiction
