Powerflex PFR5-3608 Polyurethane Rear Control Arm Mounts for BMW Z4 M E85 E86

Give your Z4 M the rear-end precision it deserves. This Powerflex PFR5-3608 polyurethane rear trailing arm mount kit replaces tired factory rubber with performance-focused bushes that hold alignment under load, cut unwanted movement and deliver a connected, confidence-inspiring drive on fast road and track.

If you are noticing rear steer, instability under braking or uneven tyre wear, these poly mounts are the proven solution. They stabilise toe change, keep geometry consistent and help the tyres stay planted for sharper turn-in and better traction.
