Steering angle

The ideal steering angle for a perfect line on all wheels when cornering varies with the speed of the car and the turning radius, owing to suspension movement and tire deformation.

Since the steering arms point slightly inwards in relation to the direction of the car, the angle of the inside wheel when cornering will be slightly greater than that of the outside wheel.
