Description

The F20 and F30 platform rear subframe bushes are a known point for excessive deflection, especially in higher power models such as the M140i and M240i. Powerflex developed this polyurethane insert to fill the voids in the standard bush, stiffening up the bush without the need for complete replacement.  Available in either standard Powerflex material or harder ‘Black Series’ material, intended for track use. This minimises subframe deflection, delivering more consistent geometry while offering compliance for road and track comfort.

Part number 20 on diagram, fits BMW part number 33316792510. Priced per pair – one pair required per vehicle. Perfect in combination with Powerflex Rear Subframe Front Bush Inserts (recommended). Covered under Powerflex’s lifetime warranty.
