Caster angle car

Dec 13, 2015 · Today we talk about caster, what it means for driver feel, and what it means for vehicle handling. Caster is very important, as it provides much needed steering feel and essentially allows the ... Castor or Caster angle Simply, caster angle is the steering axis' angle of inclination to the the vertical. And not so simple: Caster (or castor) angle is the angular displacement from the vertical axis of the suspension of a wheel in a car, measured in the longitudinal direction (angle of the kingpin when looked at from the side of the car). Caster. Caster is a bit harder to conceptualize, but it’s defined as the angle created by the steerings pivot point from the front to back of the vehicle. Caster is positive if the line is angled forward, and negative if backward. Typically, positive caster will make the vehicle more stable at high speeds, and will increase tire lean when cornering. To read CASTER first turn the wheels 20º to the right when setting the RF and to the left when setting LF. If you don't have a set of turn plates you can use the angles machined on the corners of the gauge as a reference. Turn the wheels until the angle is parallel to the side of the car. Rotate the gauge until it is level. If I place my digital angle unit on the spindle in line with the UCA/LCA I get about 4.5 degrees. If I understand caster correctly, this means I have 4.5 degrees negative caster as the UCA is ahead of the LCA (closer to front of car). This is with no shims at all. I would have expected the UCA/LCA to be almost vertical to the floor with stock ... Jun 26, 2013 · Caster is whether the bottom of the suspension is forward of the top of the suspension (positive caster) or rearward (negative caster). Usually cars have positive caster, the question is only how much of it. Caster only applies to the front (steered) axle. Most of the discussion around caster centers on steering effort. 1. Caster. Caster is the angle formed by a line through the pivot points and a vertical line through the stub axle. It can be negative or positive. Caster assists in the self-centering action of the steering; Caster is not a tyre wearing angle; Excessive variation side to side means the vehicle will pull to the side of least positive caster
