Powerflex Poly Bushes Pack - Rear Lower Arm Outer Bush - PFR5-4618 - BMW Z4M E85 and E86 2006 to 2009
Unlock sharper handling and longer lasting suspension performance with the Powerflex PFR5-4618 Rear Lower Arm Outer Bush kit for the BMW Z4M E85 and Z4M E86. This polyurethane bush kit replaces soft, ageing rubber to reduce unwanted suspension deflection, keeping your rear alignment stable under load for confident cornering, improved braking stability and more consistent tyre contact with the road.
We use Powerflex bushes on our own builds and our customers consistently report tighter rear-end control, more precise steering feel and reduced uneven tyre wear. If your Z4M feels vague at the rear, this is the proven upgrade.

Why upgrade to Powerflex polyurethane bushes

That means better road holding, safer dynamics and more predictable performance, whether you are daily driving, enjoying fast road miles or heading to the track.
