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.
Steering axis inclination is the number of degrees that a line drawn through the upper and lower ball joints (or strut and lower ball joint) and viewed from the front is tilted to the left or the right. This, in combination with caster, is responsible for the directional stability and self-centering of the steering.ositive caster means that the top of the upper ball joint (or strut) is tilted toward the rear of the vehicle, and negative caster means that it is tilted toward the front. A vehicle with a slightly positive caster setting will have its lower ball joint pivot slightly ahead of the tire's center.
