Bought a upgrade for the subframe. The polyurethane bushings are inserted into the rubber subframe bushings, which tightens them up and limit the movement in them.

Highly recommended from a performance point of view (night and day difference when cornering). But be aware, they do introduce vibrations into the cabin. It will take some time before these settle and the vibration will be lower in the end.
