Generally speaking, motor mounts are always very soft and sloppy from the factory. They provide a quiet, smooth ride that most anyone can appreciate. If you intend to get more performance out of your car whether on the street or track, the motor mounts have the ability to provide a much better performance foundation when upgraded. The stiffer bushings allow much less movement of the engine which will keep the car more balanced overall. Motor mounts will also help transfer power to the ground better, instead of into twisting in place inside the engine bay. The Damond motor mounts feature steel construction for very high strength and durability and urethane bushings for a more solid feel that isn't completely harsh.

Great performance, minimal NVH increase.
I previously had the JBR 70A PMM. After 5k, I decided the NVH was too much to deal with when DD. After I put on the Damond PMM, the NVH I previously had from the JBR PMM subsided but performance stayed nearly the same. Car no longer rattles my bones in the 2500-4000 RPM range. If you're looking for a mount that adds performance but you need your car for a comfortable DD, this is it. Worth the extra money.
Damond mounts were the number one recommended mounts. I now have the rmm and the pmm very very pleased with the addition of the pmm. The in cabin vibration seem to already be soothing out have been on the car for about 300 miles. Instal was very easy. If you’re in the market for a pmm look no further. My only complaint is that the DM logo rubbed away fairly easy.
Damond motor mounts are the only way to go
Installation was easy you will need a torque wrench. When I first started the car it didn’t get noisier then stock but the vibrations weren’t too much of a difference compared to other mounts
Big improvement over stock
Installed it yesterday and am very happy. Added very little in the way of vibrations, and it’s only slightly noisier. But the car feels so more planted than before. And I was pleasantly surprised by how easy it was to install, especially with the excellent online instructions on the DM website. I highly recommend it.
Stiff but Low vibes
My OEM PMM on my 07 MS3 decided to squirt. I did not want a ton of vibrations and noise from a new mount. This mount it great. Adds a very very small amount of vibes, but only noticeable by the driver. The mount feels way more solid than OEM. Shift feel improved as well. Also on noise. If you are driving slow, with the radio off, and have no exhaust, you can hear the slightest 'whine' noise from the mount. I mean barely... But no passenger has been able to hear it. Just me because of how well I know my car. Once the radio is on or a conversation it goes away and you can't notice it. Buy this mount. You won't regret it.
