In racing parlance, an apex is the straightest line through a curve and the path that allows the maximum speed with minimal braking. Generally, this line runs extremely close to the edge of the track, and it is not unusual for tires to clip the racetrack's rim.
As an automobile steers through a curve, gravity shifts the vehicle's weight to the outside of the curve. You can feel this force pulling you in the opposite direction of a curve or turn. Unfortunately, body roll hinders your handling because the concentration of weight on one side of the vehicle lessens traction and impairs steering. Effective antidotes to the scourge of body roll are lowering your vehicle's center of gravity, installing stiffer springs and mounting an anti-sway bar.
While most people associate the term C-section with an invasive birthing procedure that's named after a famous Roman General and epileptic, it has more than one meaning. A C-section also refers to the process of cutting out a notch from a vehicle's frame to allow proper clearance during a serious suspension lowering.
From the Latin word "camur" meaning "curved" or "bent," camber refers to the angle of your wheel. If a wheel is perfectly straight so that the top of the tire is parallel with the bottom, then it has a 0 degree camber. Negative camber is when the top of the tire bends inward, towards the vehicle. Likewise, positive camber is when the tire bends outward, away from the vehicle.
Without going into an extensive physics lecture, the center of gravity is basically a point on an object where its weight is balanced and in harmony. Adjusting an automobile's center of gravity by lifting or lowering its suspension has profound effects on handling, steering and cornering.
Sometimes called the "pumpkin," a differential is the round hump in the middle of an axle. More than just decorative, the differential houses a set of gears that transmits torque energy out to your tires and allows them to spin at different speeds during turns.
Anyone who has ever seen a corkscrew or a spring has seen a helix-it's simply a spiral. Basic as it may seem, life as we know it would be radically different (if existent at all) if not for the helix. That's because DNA and many proteins form helical shapes, which in turn dictate how we and the world are shaped.
Closely related to words like "jolt" and "bounce," jounce refers to the up-down motion of a wheel that hits a bump.
The economic system championed by Adam Smith and perfected by Enron, laissez-faire refers to free market economics in which government regulation is slim or non-existent. This hands-off system reached its heyday during the industrial revolution, fell out of favor during the Great Depression, and was later revived by such world leaders as President Ronald Reagan and General Augusto Pinochet.

Legally, a vehicle manufacturer cannot void the warranty on a vehicle due to an aftermarket part unless they can prove that the aftermarket part caused or contributed to the failure in the vehicle. If your vehicle manufacturer fails to honor emission/warranty claims, contact EPA at (202) 260-2080 or www.epa.gov. If federal warranty protection is denied, contact the FTC at (202) 326-3128 or www.ftc.gov.
One of the most essential components in your steering system, the pitman arm connects the steering box with the drag link. In other words, the pitman arm transfers the motion of your steering wheel down to the linkage that navigates your wheels. Often, a lift kit changes the distance between the steering box and the drag link, so a longer pitman arm is needed.
