One of the most overlooked modifications for the Z and G chassis is replacing worn subframe bushings. A large amount of suspension dynamics is compromised when energy is transferred to the shifting subframe instead of being directed towards the dampers. Replacing tired and old rubber bushings with these solid anodized aluminum bushings will result in better suspension feel and response that a driver yearns for.
Removing stock bushings and replacing solids is not an easy task, but well worth it.
