you have couple options, you can either replace your bushings with 3 basic types of bushing material: Rubber, Polygraphite or Delrin. If you are looking to renew your car’s ride to “factory type handling” which is good for daily driving and cruising, rubber bushings are the way to go. Rubber Is great at acting as a insulator between you and the road and this provide a quality/comfortable ride. But rubber has its downfalls to. The main thing is that it dampens by deflection and deflection affects response of your suspension or how quickly it reacts to changes in the road. The way to combat this is with the material Polygraphite. Polygraphite is polyurethane that was been mixed with graphite so that is self lubricating. What makes Polygraphite better than conventional rubber is its durometer rating or the rate at which it compresses. Less compression yields less deflection which equals better response, more feel of the road and less body roll, meaning firmer planting of the tire on the road. Polygraphite is a happy medium between rubber and delrin as it has a slight give to it so the ride is not harsh but not yet as firm as delrin. The best way to describe Polygraphite is that your muscle car will have a modern day car feel/handling. Polygraphite is ideal for street and track use. Delrin is best for track use. It has minimal gives and allows a fluid motion through the suspensions range of motion, but lacks ride quality. The ride tends to be harsh and you will feel every imperfection in the road.
