Uprated rear crossmember mounting bushings for BMW 1 Series E81, E82, E87, E88

Transform rear-end composure on your E8x with the Powerflex PFR5-422 polyurethane bushing set. This pair of full replacement rear crossmember rear mounts swaps out tired factory rubber for precision-engineered PU that tightens up the back axle carrier, stabilises geometry and makes your 1 Series feel planted, predictable and more responsive on road and fast-road drives.

Why upgrade

• Crisper turn-in and more consistent handling under braking, cornering and acceleration
• Reduced unwanted sub-frame movement for truer alignment and improved traction
• Better high-speed stability and steering feedback without the slop of ageing OE rubber
• More even tyre wear thanks to controlled rear axle location
• Durable polyurethane designed to balance control and comfort, backed by Powerflex Lifetime Warranty

• Diagram reference: 20
• BMW OE cross-reference: 33316758260

How it works

Standard rubber mounts flex and degrade, letting the rear cradle wander and upsetting alignment. Powerflex polyurethane significantly limits that movement so the suspension can do its job properly. Expect more grip, better braking stability and a connected rear end that inspires confidence on B-roads and daily use alike.

Proven in our workshop

We have installed PFR5-422 on customer cars and our own builds, and the feedback is consistently positive. Owners notice the immediate step-up in rear-end precision and overall control. It is a simple, high-impact upgrade that feels great from the first drive.
