Wheel alignment is not all that physically difficult or difficult to understand - just a very specialized equipment is needed to determine the angle of inclination of the wheel. After that, it's just that all the bolts and adjust the rotation, until you get all of that in the specifications. Some get a little bit here and there can make the difference between a car that provides a predictable, reliable performance, and one that chews through tires and every drop of fuel is restored just before hitting a tree.
2. Camber
Camber refers to bend inward or outward of the tire. Completely
vertical tire has no camber, or zero degrees camber. One which
protrudes at the top has a certain degree of positive fit, while the
one which tilts inwardly inclined downward. Negative camber
helps keep your tires planted at the turn, but reduces the braking
and acceleration and stability at high speed. Positive camber -
outward tilt - has no real advantages in terms of handling,
braking, acceleration or stability. Excess negative camber make
your tires wear faster than the inside of the outer edge, and a
positive camber will be discharged faster at the outer edge.
3. Caster
Imagine looking at the rim side and then draw an imaginary line
from the top of the ball joint through the lower joint all the way to
the ground. Now imagine a vertical line is completely straight
through the center of the wheel. You will see that a line drawn
through the ball joints hits the ground, just in front of the vertical
line. The ball joint line is your wheel's pivot axis, while the
vertical line, which applies the tire force. The greater the
distance between the pivot line and the vertical line - the more
advance angle - the harder the wheel would attempt to center
during rotation. More advancing angle is greater steering effort,
but the result is increased speed stability and better steering
precision and feedback.
4. Toe Angle
Imagine standing on the hood of your car's windscreen with your
body forward, your eyes looking down at the wheels. If you could
see the tires through the fenders, you understand that you
probably do not indicate on the front; or good angle to each other
in the front or at a distance from each other. If the wheels point to
another in a state of convergence that will always try to pull the
car to the center. This increases stability at high speed, but painful
treatment response. Toe-out can help make the car more flexible,
but can also make it a bit twitchy. Zero toe, or completely parallel
adjustment, improves fuel efficiency and tire life, because the tires
are not moving sideways - known as scrubbing - as you drive
down the road.
