Rear Stabiliser Bar Mounts 15 mm for BMW 4 Series F32 F33 F36 – Powerflex PFR5-1913-15

Transform the way your BMW 4 Series turns in and holds a line with this high-performance polyurethane rear stabiliser bar mounting kit. Engineered by Powerflex to control unwanted movement at the back of the car, these 15 mm bushes tighten up the chassis, enhance feedback through the wheel and keep the car flatter through bends for confident fast-road driving and track use.

We fit these on customer cars at MJ Modifications and the results speak for themselves. Sharper response, calmer body control and more consistent tyre contact make the car feel planted without ruining road comfort. A simple, affordable upgrade that outlasts tired factory rubber.
