TRD Lower trans mount and noise/vibration?

[ZAKU]

I want to buy one of these:

But I've heard that replacing the lower mount with poly can cause a fair bit of noise and vibration.

Is the TRD closer to stock because it is stiffer rubber? I don't mind a little extra noise and vibration but this is my daily driver with just a couple bolt ons.

You will get a little extra noise and vibration. Especially noticeable when you start the car (starter turning it over). It is better than poly and you will feel the difference in your shifts and when you accelerate (shuts down engine movement).
