Powerflex poly bushes improve your cars road holding and chassis performance by controlling the amount of unwanted flex in the suspension. This means your suspension is doing what it is supposed to. This equates to your tyres having greater contact with the road at all times therefore improving safety and performance. Correctly formulated polyurethane is as good if not better at noise, vibration and harshness suppression when compared to rubber.
