The use of the air valve takes getting used to. Bottom Line: Yes, I would recommend this to a friend
A positive caster angle produces a self-centering action of steering, and gives a steering feedback for the driver in straight line. This makes a vehicle easier to drive with a better steering response and directional stability.ue to this caster angle, a power steering is usually used by manufacturers. With a positive mechanical trail, the wheel is âpulledâ by the vehicle as a wheel of a shopping trolley. Thus, it produces a self-righting effect in straight line which affects the vehicleâs straight-line stability.
Usually SAI is a built-in angle and is not adjustable in the alignment shop. The effect of the SAI is illustrated in Fig.1. Turning the steering wheel, results in the car body being slightly pushed up. Then the weight of the vehicle generates the force returning the wheel into the central position.As can be seen from the geometry of this arrangement, such self-centering force is non-linear by nature.sually SAI is a built-in angle and is not adjustable in the alignment shop.
