Energy Suspension Control Arm Bushing Set - If your car's handling seems a bit on the sloppy side lately, replace your mushy rubber bushings with Energy Suspension's Control Arm Bushing Sets. Because polyurethane is unaffected by oil, smog, road salt, or most chemicals, it doesn't soften, compress, or distort like rubber does

The installation of these bushings was fairly straight forward and the documentation was easy to follow. The install process only required hand pressure for the bushings and a C-clamp for the metal inserts. Each bushing has a number stamped on it which corresponds to a diagram for proper placement. My only gripe is the fact that the metal inserts had no identifying properties. Energy suspension simply gives you their measurements and expects you to measure them out. I would have given these 5 starts but I didn't feel the amount of lube they supplied was sufficient. Overall, a very good product.
