Positive caster increases align torque, aka the force that straightens the steering wheel when you go forward, which improves straight line stability of the car. Due to the geometry of positive caster this will also increase negative camber gain when turning, which will enable a wider tire contact patch. The caster angle is a major contributor to directional control. An insufficient amount of positive caster angle will decrease driver effort at the steering wheel, but may make the vehicle too sensitive and twitchy, especially as speed increases. To achieve the best on-the-road driving experience, recommended front axle caster setting is 7 degrees positive.
