Whiteline Rear Lower Inner Wishbone Bush Kit for BMW E46 3 Series and Z4 E89

Refresh the back end of your BMW with Whiteline’s performance-grade rear lower inner wishbone bushes. Perfect for E46 3 Series and Z4 E89 owners looking to sharpen handling and restore precise suspension geometry, this bush kit replaces tired factory rubber with Whiteline’s advanced synthetic elastomer for crisp, consistent road feel.

If you’re noticing vague behaviour mid-corner, poor stability on throttle, tramlining or accelerated inner-edge tyre wear, worn rear arm bushes are a common culprit. This direct-fit solution tightens up the rear axle, helping your alignment stay true under load for more confidence on B-roads, commuting and track days alike.

Why choose this Whiteline bush kit

  • Performance elastomer compound resists deformation for improved chassis control and predictable dynamics.
  • Helps maintain rear camber and toe settings under braking and cornering for better grip and tyre life.
  • Engineered for durability, oil and heat resistant, and a clear step up from ageing OEM rubber.
  • Precise fitment for the rear lower inner arm location on BMW 3 Series E46 and BMW Z4 E89.
  • Ideal for fast road and track enthusiasts wanting a sharper, more connected drive.
