E46 Engine mounts - M3, polyurethane, other ?

[Cement 875]

I'm about to start making the new mounts for my engine swap project and will be using the BMW mount with a new bracket from there to the engine. I'd like it to not move around too much as clearances are tight in places ... so I'm wondering if people have had any experiences with M3 mounts or polyurethane etc and have a recommendation either way ?

Its ultimately a street car so not looking to increase noise and vibration any more than necessary.

I use these, pretty trick and no extra NVH:

Otherwise I'd go for M3 mounts, depends on how deep your pockets are feeling.
