Why polyurethane

Ageing OEM rubber allows excess movement that leads to imprecise handling, braking instability and premature tyre wear. Correctly formulated polyurethane controls flex in the suspension while maintaining excellent noise, vibration and harshness suppression. The result is performance and comfort, together.
