BMW Subframe Mount Insert Set - Powerflex Street PFR5-4612

Enhance the rear end stability and handling of your BMW E46 M3 or E85/E86 Z4 M with the Powerflex Street Subframe Mount Insert Set (PFR5-4612). These high-performance polyurethane inserts are specifically designed to fill the voids within your factory rear subframe bushings, significantly reducing unwanted movement.

By minimizing subframe deflection, this Powerflex Street series kit improves power transfer to the wheels, sharpens throttle response, and provides more precise handling. Experience a more connected and controlled driving feel, ideal for spirited street driving and occasional track use, without the harshness of full race-spec components.

This set is engineered for a direct fit into the rear left and right forward subframe positions. It is compatible with 2001-2006 BMW M3 (E46) and 2006-2008 BMW Z4 M Coupe/Roadster (E85/E86) models equipped with the 3.2L S54 engine. Upgrade to Powerflex for a noticeable improvement in your BMW's dynamic performance.
