Your car's suspension is a grouping of individual components that work together to connect the vehicle to its wheels. These aspects include shock absorbers and struts. The suspension is all about finding the right balance so that your car drives smoothly. You do not want your car to bounce every time you go over a speed bump, but you also want it to absorb some of the motion.
The ultimate goal of your car’s suspension is to maximize the friction between the tires and the road surface, while at the same time providing steering stability and ensuring passenger comfort. Perhaps if roads were completely flat, there would be no need for suspension, but all roads have imperfections and irregularities that require suspension to work.
