A wheel alignment angle that refers to the forward or rearward tilt of the steering axis on the front wheels (See Alignment) A forward tilt of the steering axis is called "negative" caster while a rearward tilt is called "positive " The caster angle has no affect on tread wear but it does affect steering return and stability Most vehicle have a certain amount of positive caster The higher the caster angle the more steady the car feels at high speed (Mercedes, for example, uses a very high caster setting) But the higher the caster angle, the greater the steering effort The caster angle on many strut suspensions is fixed at the factory and is not adjustable
The angle between the steering axis and the vertical, as viewed from the side It is considered positive when the steering axis is inclined rearward at top
The forward or backward tilt of a car's front wheels that, when aligned properly, will make them follow naturally in a straight line The caster setting is what helps the car return to straight after turning a corner
(Otomotiv) The forward or backward tilt of a car's front wheels that, when aligned properly, will make them follow naturally in a straight line. The caster setting is what helps the car return to straight after turning a corner
The deviation from vertical of the axis about which the front or steering wheels pivot Caster is termed "positive" when the steering axis is tipped toward the rear of the vehicle, and "negative" when this axis tips toward the front of the vehicle
Almost every car has some caster built-in Caster is the angle that the car's front wheels pivot on when turning Most on-road Touring Car type kits use between 5 and 10 degrees of caster Off-road kits like buggies and trucks have about 25 to 30 degrees of 'kick-up' on the front axles More caster generally gives more steering going into a turn, but less coming out The opposite is also true: less caster give less steering going into a turn (initial steering), but more steering as you exit Caster also gives more stability on straightaways, but this effect is more pronounced in 2WD vehicles
Another measure of chassis tuning related to the front wheels The front wheels are attached to the suspension at the top and bottom of the wheel assembly The top attachment is typically set a little farther back than the lower attachment, creating caster The more caster used, the more the wheel resists turning forces, providing stability Too much caster makes it very difficult to steer, and causes the tire camber to change significantly as the wheel is turned Not enough caster results in the front end "wandering," or trying to turn on its own
The inclination of the kingpin as seen from the side If the top of the kingpin is tilted rearward this contributes the steering's tendency to return to center
this is the angle that the front kingpin makes to in relation to the imaginary line perpendicular to the ground Increasing caster increases steering entering a turn, but decreases steering exiting a turn Decreasing will have the opposite effect
Very often confused with kingpin incline because the axle is set back from the kingpin Adding kingpin incline reduces caster angle! Having 0° kingpin incline gives most caster this helps the car straighten up coming out of a bend, adding kingpin incline reduces this
The angle, from vertical, of the kingpin in relation to the ground Caster can have a great effect on how a vehicle enters and exits turns and corners Increasing positive caster, so that the kingpin is angled back, will generally increase steering going into a corner and a slight decrease in steering coming out Less positive caster will decrease the amount of steering going into a corner, but will increase the amount of steering in the middle and while exiting that corner

An alignment spec where an imaginary line through the ball joints (steering axis) intersects a vertical line through the front wheel center Positive caster delivers directional stability and improved steering feel
Chassis : Relative position of the top A-arm ball joint to the bottom A-arm ball joint In ATVs, the top A-arm trails slightly behind the bottom A-arm (positive caster)
