Powerflex PFF5-1002 Poly Bush Kit - Front Lower Control Arm/Wishbone Inner Bushes (Pair) for BMW 5 Series E60 & E60 M5 | Front Suspension Inner Mount Bushing Upgrade | Replaces OE 31122347963

PFF5-1002 Poly Bush Set for BMW E60 5 Series and E60 M5 - Front Wishbone Inner Mounts

Transform the front-end feel of your E60 with the PFF5-1002 polyurethane inner mounts for the front suspension arm. By replacing tired factory rubber, these premium poly bushes stabilise the front axle, tighten up steering response and keep alignment consistent under braking and cornering. Expect cleaner turn-in, better mid-corner support and more confidence on B-roads and motorways alike.

Manufactured from high-grade polyurethane that resists oil, salt and heat, this bush kit delivers long-term precision where OE rubber quickly softens. Road comfort remains civil, while directional stability and tyre wear improve thanks to more controlled geometry.

Key benefits

• Firmer front end bite and more accurate steering input
• Reduces arm movement to keep camber and toe stable under load
• Helps reduce tramlining and improves braking feel
• Durable material outlasts standard rubber in harsh UK conditions
• Ideal for fast-road daily drivers and enthusiast builds
• Backed by the Powerflex Lifetime Warranty

Workshop feedback

We have installed this kit on multiple customer cars and the difference is immediate - sharper steering, improved stability and a more planted front end. A small change that makes the whole car feel more precise.
