Powerflex Rear Stabiliser Bar Mount Bush Kit 14 mm for BMW E8x, E9x xDrive, E84

Transform rear axle control and tighten up chassis feel with this pair of Powerflex polyurethane bushes designed for the rear stabiliser bar. Engineered to replace the tired factory rubber (OE ref 33556761568), these 14 mm ID bushes cut unwanted movement, reduce roll in corners and help the car put power down cleanly on rough UK roads. Ideal for daily driving, spirited B-road use and fast-road setups where precision and confidence matter.

We run these bushes on our own vehicles and fit them for customers every week. Feedback is consistently strong with sharper turn-in, a calmer rear end over bumps and more predictable grip compared to ageing rubber mounts.

Key reasons to upgrade

• Uprated polyurethane controls flex in the rear bar mount for cleaner geometry under load
