Whenever you change the materials used for suspension or motor mounts/trans mounts you will change the harshness levels. I remember changing A arm bushings and end links and it substantially increased NVH to the point of uncomfortable daily but great for racing. Sacrifices are made with parts like this, especially when companies like ford spend thousands in engineering vs aftermarket/homemade spending almost zero. The 18/19 mount is a huge upgrade from the previous one. And it's only 40$ or so. But it isn't perfect, so there is still some room for improvement. It doesn't add any NVH though, so it still feels and sounds like a luxury car.
