Upgrade the rear suspension on your BMW Z4 E89 with Powerflex PFR5-4618 Rear Lower Arm Outer Bushes. These performance polyurethane bushes replace soft, ageing rubber to deliver sharper handling, better stability and a more precise driving feel. Ideal for fast road and track day use, this popular Z4 rear lower arm outer bushing kit helps control unwanted suspension movement, keeps alignment stable under load and maximises tyre contact for improved grip and confidence.

Why choose Powerflex polyurethane bushes for your Z4 E89

  • Improved handling and steering response by reducing flex in the rear lower control arm outer joint
  • Better braking stability and cornering precision thanks to consistent suspension geometry
  • Reduced and more even tyre wear due to improved camber control and alignment retention
  • Durable, long-lasting polyurethane that resists oil, road grime and ageing far better than rubber
  • Excellent NVH control when correctly formulated, comparable to OEM rubber in everyday use
  • Outstanding value upgrade for performance driving, daily use and track days
  • Backed by the Powerflex Lifetime Warranty

What you get

  • 2 x Powerflex Rear Lower Arm Outer Bushes - PFR5-4618
  • Designed specifically for BMW Z4 E89 2009-on
