Powerflex PFR5-4616 Uprated Polyurethane Bush Kit for BMW E46 Platform including M3

Transform the way your E46 drives with the Powerflex PFR5-4616 rear lower arm inner bush set. These performance-grade polyurethane bushes replace tired factory rubber, tightening up the rear axle so your BMW tracks straight, holds alignment under load and delivers crisp, confidence-inspiring response.

We have fitted PFR5-4616 on our own builds and for many MJ Modifications customers, and the feedback is consistently excellent. Expect cleaner turn in, greater mid-corner stability and more even tyre wear with dependable geometry control.

What you will notice

If your E46 feels vague at the rear, wanders on uneven surfaces or wears tyres unevenly, worn inner arm bushes are often to blame. Powerflex polyurethane stabilises the inner pivot, keeping toe and camber consistent so the chassis behaves exactly as intended.

Professional fitting and alignment

We recommend professional installation followed by a full four-wheel alignment to maximise performance and tyre life.
