Why upgrade this mounting point

As factory bushes age, they soften and deform which can cause vague steering, tramlining and uneven tyre wear. These polyurethane arm rear mount bushes minimise unwanted movement at the pivot, maintaining caster and toe under load. The result is a more connected front axle, a stronger contact patch and a more stable car when braking and cornering.

Fitment details
