Powerflex PFF5-1901 Polyurethane Front Caster Arm Rear Bushings for BMW F-Series

Transform front-end precision and confidence with the Powerflex PFF5-1901 polyurethane bushing set. This upgrade replaces the soft factory rubber in the front caster arm rear position, giving your BMW F-series sharper steering feel, improved braking stability and more consistent geometry when pushing on. Perfect for enthusiastic road use and fast-road setups where accuracy, feedback and tyre life matter.

We run PFF5-1901 on our own cars and customer feedback has been outstanding. Expect tighter turn-in, reduced wander on uneven surfaces, better alignment control under load and a more planted front axle without harshness. It is a direct swap for tired OE mounts, engineered to deliver long-term performance you can rely on.

Why upgrade to Powerflex PFF5-1901

  • Sharper steering response and cleaner feedback through the wheel
  • Greater stability when braking and cornering
  • Holds camber and caster more consistently for better tyre wear
  • Durable polyurethane construction designed for UK roads
  • Direct replacement for factory rubber bushes
