Why choose these Powerflex Black Series polyurethane bushes

  • Black Series material increases stiffness by 18 percent over the original rubber bush to better control suspension geometry under load.
  • Fixed 5 mm offset delivering approximately ±0.5 degrees caster change for a crisper steering feel and improved straight-line stability.
  • Additional caster promotes extra negative camber on turn-in, improving front-end grip and tyre contact patch under heavy cornering.
  • Polyurethane construction reduces unwanted flex compared to ageing OEM rubber, helping reduce uneven tyre wear and braking instability.
  • Excellent noise, vibration and harshness control when correctly formulated, while significantly improving chassis precision.
  • Backed by Powerflex Lifetime Warranty.

Real-world results

We have fitted and used these Powerflex bushes on F80 M3 builds and customer cars. Feedback has been consistently positive, highlighting noticeably sharper steering response, greater confidence on turn-in and more consistent tyre wear for both spirited road driving and trackdays.

  • BMW F80 M3 owners wanting a handling upgrade without excessive NVH.
  • Fast-road, trackday and performance-focused builds seeking improved caster and camber behaviour.
  • Replacing soft, ageing or failing rubber bushes that cause imprecise handling and braking instability.
