Powerflex Polyurethane Rear Lower Suspension Control Arm Outer Bush Kit PFR5-4618 for BMW Z4M E85/E86 2006-2009 (Set of 2) Replaces 33326771828

Precision rear-end grip for BMW Z4 M E85 and E86

Transform the way your Z4 M turns in and puts power down with this uprated rear lower wishbone outer pivot bushing kit. Powerflex PFR5-4618 replaces the tired factory rubber at the hub end of the rear lower link, locking in geometry so toe and camber stay where they should under braking, acceleration and hard cornering. The result is cleaner feedback, reduced rear steer and confidence on fast road and track.

We run these on our own builds and our customers love the difference: crisper response, calmer rear axle over bumps and more even tyre wear. If the back of your Z4 M feels vague or is scrubbing tyres, this is the go-to fix that lasts.

Why choose this upgrade

• Direct-fit replacement for the hub-side pivot on the rear lower link, no machining required
