Car hydraulics are equipment installed in an automobile that allows for a dynamic adjustment in height of the vehicle. These suspension modifications are often placed in a lowrider, i.e., a vehicle modified to lower its ground clearance below that of its original design. With these modifications, the body of the car can be raised by remote control.
Damping controls the travel speed and resistance of the vehicle's suspension. An undamped car will oscillate up and down. With proper damping levels, the car will settle back to a normal state in a minimal amount of time. Most damping in modern vehicles can be controlled by increasing or decreasing the resistance to fluid flow in the shock ...
Stiffer valve springs can help prevent valve float and valve bounce but at the expense of increased friction losses, higher stresses, and more rapid wear in the valvetrain. Various techniques have been used to offset the effect of stiffer springs, such as dual-spring and progressive-sprung valves, roller-tipped tappets, and pneumatic valve ...

Hard-cut limiters completely cut fuel or spark to the engine. These types of limiters activate at the set RPM and "bounce" off of it if throttle is applied. This phenomenon is referred to as hysteresis. The "bouncing" occurs because the limiter will cut off fuel or spark at the set RPM, which causes the RPM to drop.

Car tuning is the modification of a car to optimise it for a different set of performance requirements from those it was originally designed to meet. Most commonly this is higher engine performance and dynamic handling characteristics but cars may also be altered to provide better fuel economy , or smoother response.
