Polyurethane Rear Subframe Mount Insert Kit for BMW 2 Series F22 and F23 – Powerflex Road Series

Give your BMW 2 Series a tighter, more planted rear end with this pair of Powerflex polyurethane inserts for the rear carrier mounts. By limiting cradle deflection in the OE rubber mounts, these inserts sharpen rear axle response, reduce squirm under load, and improve stability on fast A-roads and motorways without a harsh ride. A simple, high-value handling upgrade for daily driving, fast-road use and spirited B-road blasts.

Key gains

• Limits rear cradle movement for cleaner power delivery and better traction
• Improves turn-in and rear-end composure under braking and cornering
• Helps reduce wheel hop and enhances mid-corner stability
• Minimal change in cabin noise and vibration compared to solid bush replacements
• Can aid tyre wear consistency and overall chassis balance

Fitment and compatibility

Designed for BMW 2 Series F22 and F23 models. Inserts locate into the cavities of the factory rear subframe rear mounts for a precise, hassle-free upgrade.
