BMW Rear Subframe Rear Mounting Insert - Powerflex Street PFR5-421

Upgrade your BMW's rear suspension performance with the **Powerflex Street Series Rear Subframe Rear Mounting Insert (PFR5-421)**. Engineered from high-performance polyurethane, this insert is designed to precisely fit the rear mounting points of your vehicle's rear subframe.

Factory rubber bushings often lead to excessive subframe movement, resulting in vague handling, reduced power transfer, and irritating wheel hop. The Powerflex Street Series insert significantly reduces this deflection, providing a firmer, more controlled feel without the harshness often associated with track-focused parts. Expect improved throttle response, enhanced cornering stability, and a more direct connection to the road.

This essential upgrade is compatible with a wide range of BMW 1-Series (E81, E82, E87, E88) and 3-Series (E90, E91, E92, E93) models from 2006-2013, including 128i, 135i, 325i, 325xi, 328i, 328xi, 328i xDrive, 330i, 330xi, 335i, 335xi, 335i xDrive, and 335d.
