Make your BMW feel more positive with the new PFR5-423 rear subframe inserts from Powerflex. They’re designed to replace the original bushing and fill the void area, creating a more solid mount. This cost effective upgrade holds the rear subframe in position more effectively, reducing movement under hard cornering. The insert is designed for manual BMW 1-Series, while E9X 3-Series are taken care off by PFR5-421.
