Why upgrade these mounts

Ageing rubber allows excess movement that leads to vague steering, clunks over bumps and uneven tyre wear. This premium polyurethane bushing set controls flex at the mounting points so the stabiliser bar can do its job properly. Expect a more planted feel in quick direction changes and more predictable chassis behaviour without a harsh ride. Poly bushes are highly resistant to contamination and deformation, maintaining performance far longer than standard parts.
