Powerflex PFR5-4609-15 Rear Anti Roll Bar / Sway Bar / Stabiliser Bar Bushes 15mm (Pair) for BMW 1 Series E81 E82 E87 E88 | Polyurethane ARB Mount Bushings | E8x | OE 33556761360

Rear stabiliser bar mount bushes for BMW 1 Series E81, E82, E87, E88 — Powerflex PFR5-4609-15, 15 mm, supplied as a pair

Upgrade the back end of your 1 Series with durable polyurethane stabiliser bar bushes that keep the rear axle planted, sharpen steering response and enhance cornering confidence. This set replaces tired factory rubber with a firmer, long‑lasting poly compound that resists deformation, heat and road contaminants, delivering consistent handling on fast road use and daily driving alike.

We run these on our own cars and customer builds, and the feedback is consistently positive. Expect a crisper feel from the rear, improved traction over uneven surfaces and more predictable behaviour when turning in or accelerating hard out of bends. It is a proven, great value chassis upgrade that transforms how the car responds without adding unwanted harshness.
