Powerflex PFR5-711 14mm Rear Lower Control Arm Rear Bush Kit (Pair) - Polyurethane Control/Wishbone/Lower Link Bushings for BMW 5 Series E60 Saloon, E61 Touring & E39 M5 (14mm Bolt) - Performance Poly Bush Upgrade - Lifetime Warranty

Powerflex PFR5-711 Polyurethane Rear Arm Bush Kit 14 mm Sleeve

Dial in precision and confidence from the back end of your BMW with this genuine Powerflex PFR5-711 bush kit. By replacing tired rubber with performance polyurethane, these rear arm mounts control unwanted movement at the rear lower link rear position, keeping alignment stable under braking and acceleration for sharper steering feel, improved traction and consistent tyre contact.

We have installed this kit on customer cars and our own builds with excellent results. Expect a more planted rear axle, greater stability in fast direction changes and tidier tyre wear over time. It is an ideal fast-road refresh and a rock-solid alternative to ageing OEM rubber.

• Resistant to oil, road salt and heat for long service life
• Balances control with comfort to minimise unwanted NVH compared with worn rubber
• Backed by the Powerflex Lifetime Warranty for long term value
