To discover exactly how much Ackermann is required in a typical stock car, we used a very accurate coordinate geometry software program to calculate the steering angle difference between the two front tires needed for a 11/44 and 1/2 mile racetrack. We then translated the angles into decimals of inches of toe.We can see that for a 1/2-mile track we would need only about 1/64 inch (or 0.03 degree) of additional toe, so the tire would follow the needed track due to the difference in radius between the front wheels.For a "tight" 1/4-mile track, we need slightly more toe again, or about 11/416 inch (or 0.11 degree) of additional toe. These numbers represent fractions of degrees of Ackermann, not whole degrees. Remember, each degree of Ackermann is a full 1/2 inch of toe.
