This has definitely been my experience, albeit with different platforms. My autox E30 has poly engine mounts and RE rubber trans mounts. NVH is entirely streetable. Years ago, I installed UUC poly trans mounts on an E46 with stock engine mounts. NVH was horrible...buzz bomb city. I drove the car 4 blocks, turned around, and pulled them off.
