BMW Rear Subframe Mount Front Insert - Powerflex Race PFR5-521BLK

Optimize your BMW E39's handling with the Powerflex Race Rear Subframe Mount Front Insert (PWF-PFR5521BLK). Engineered as part of the high-performance Powerflex Black Series, this insert is designed to dramatically reduce unwanted movement in your rear subframe.

By filling the voids in the factory front subframe bushings, it provides a much firmer connection between the subframe and chassis. Experience enhanced power transfer, significantly improved chassis response, sharper turn-in, and superior rear-end stability. Crafted from a harder durometer polyurethane, this race-spec insert is built for the demands of track driving and spirited road use, virtually eliminating subframe deflection under heavy acceleration and cornering.

This essential upgrade offers a more connected and predictable driving experience, making it ideal for performance enthusiasts and motorsport applications. It's a direct fit for BMW E39 525i, 528i, 530i, 540i, and M5 models from 1997-2003. Upgrade to Powerflex Race for ultimate precision and control.
