Poly Bush Rear Stabiliser Bar Mounts 13 mm for BMW E81 E82 E87 E88, E9x xDrive E90 E91 E92 E93 and X1 E84 - Powerflex PFR5-4609-13

Transform the way your BMW turns in and holds a line with this uprated rear stabiliser bar bushing pair. Powerflex PFR5-4609-13 replaces tired factory rubber with high-quality polyurethane for crisper response, flatter cornering and more consistent geometry under load. It is a simple, high-impact chassis upgrade suited to daily driving, fast road use and track-prepped road cars.

We run these poly bushes on our own builds and customer cars, and the feedback is consistently positive. Expect a tighter rear end, improved stability through quick direction changes and long-lasting performance that resists oil, salt and road grime far better than standard rubber mounts.
