One of the best and most economical ways to improve performance is to replace factory rubber bushings with polyurethane bushings. The perfect hardness of polyurethane bushings provides for quick and precise control. Factory rubber bushings are soft and give under load, causing the steering and suspension components to bind. Polyurethane bushings are free floating and non-binding which allows the suspension to work more smoothly. Below are some examples of what we mean
