Why choose PFF5-5601G for your BMW Z4M E85 or E86

  • Additional +0.5 caster versus PFF5-5601 for better straight line stability, improved self centring and sharper turn in.
  • Hard anodised aluminium outer shell with a unique low friction polyurethane centre bush for a true rotating action that reduces binding and lowers loads on the arm.
  • Lower arm deflection is reduced by minimising compliant material inside the aluminium shell, so geometry stays stable under braking and cornering.
  • Tested stiffness gains of 128 percent over the original rubber bush for precise steering feel and control.
  • Black Series option increases stiffness by a further 28 percent to deliver a 190 percent increase over the original part.
  • Durable polyurethane construction with excellent noise, vibration and harshness control compared to ageing rubber.
  • Lifetime Warranty from Powerflex for long term peace of mind.
