Powerflex Rear Stabiliser Bar Clamp Bush Kit 18 mm - PFR5-4609-18 - BMW E60 5 Series and M5

Upgrade the rear end of your BMW E60 and E60 M5 with this premium polyurethane stabiliser bar bush kit from Powerflex. Designed to replace tired factory rubber, these rear bar bracket bushes tighten up the chassis, reduce body lean, improve steering precision and help the tyres stay planted. Expect a more confidence-inspiring drive with better composure in fast corners and superior stability under braking.

We fit these on our own builds and for customer cars at MJ Modifications. The feedback is consistently positive, with owners reporting cleaner turn-in, improved mid-corner support and a more connected feel without unwanted harshness. Powerflex polyurethane controls movement where it matters while managing noise and vibration to a level comparable to OE.
