Upgrade your BMW 1 Series F20 F21 with the Powerflex Black Series rear subframe rear bush insert. Designed for track and motorsport use, this high-performance polyurethane insert fits into the voids of the original OEM bush to reduce subframe movement and deliver sharper handling, improved stability and more consistent chassis control.
