Powerflex PFR5-411 Rear Arm Mount Kit for BMW 1 Series E81, E82, E87, E88

Give your E8x rear end the precision it deserves. This Powerflex PFR5-411 rear arm bushing set replaces tired factory rubber with high-grade polyurethane, tightening up the back axle for crisp responses and dependable stability. Expect a more planted feel through bends, improved confidence when you hit the brakes and a consistent alignment that keeps the car tracking straight.

What you will notice

• Cleaner steering feedback and sharper turn-in from reduced arm movement
• Better grip and braking confidence thanks to improved tyre contact
• More consistent geometry that helps reduce uneven tyre wear
• Polyurethane durability that outlasts ageing rubber
• Balanced control of noise, vibration and harshness for daily use
• Covered by the Powerflex Lifetime Warranty

Perfect for fast road or daily driving

Whether you are building a fast-road E8x or simply refreshing a tired rear axle, this kit delivers a noticeable upgrade without compromising comfort. We run these bushes on our own cars and customer builds, and the feedback is always the same: tighter, calmer, more confidence-inspiring.
