Fitment and install notes

These inserts are designed to locate neatly into the cavities of the original mounts on F10 and F11 models. Many users fit them with the mounts still on the car, making this a quick and effective drivetrain upgrade. Firming up the connection between engine and chassis can slightly increase noise and vibration at idle, which is normal for performance inserts.
