A cars suspension is what allows it to ride smoothly, travel over various bumps, cracks, and other surfaces. There are many components to a cars suspension, and each make and model is slightly unique from one another. The main components consist of the struts and springs, as well as swaybars and endlinks. There are a few other notable components which include inner and outer tie rods, as well as control arms. All of these components wear out with age and mileage. I chooose to replace my struts and springs with coilovers which essentially combine a strut and spring together in one unit. This way, I am now able to adjust my cars ride height, suspension stiffness, and other suspension. dynamics.
