tranny and motor mounts

One of my first mods was a Group N tranny mount. I have to say for ~$60 it can't be beat. Took the "thunk" out of the drivetrain. It is relatively easy to intall. As for motor mounts, they increase NVH way more than the tranny mount does alone and didn't make as big a difference as the tranny mount alone did. Not worth the price IMHO.

I guess you could say since less movement is transmitted to the tranny and engine that more power is transmitted to the wheels but it would hardly be noticable in acceleration test or dynos. It's a feel thing. Car just feels a little more solid during shifts.

Neither of the mounts really do anything in terms of performance, I think. The only benefit is the "feel" of the car. While tranny mount really does elimite the "thump", the engine mounts really do not do anything besides making the car feel rough and shake at idle.
Of course, stock mounts are more prone to tearing and I think that is why there are those Group N mounts. After all, who would want their engine flop around on torn mounts during a rally.
At some point I had some motorsports only CUSCO mounts and the whole car felt rough. I got used it it, but anyone who would drive my car, would complain about them since so much noise and fibration would be transferred through them.
Now I have the STi tranny and engine mounts and I am going to take the engine mounrs out to make my car more civil.

Rather then get the motor mounts which transfer all of the vibration from the motor to the rest of the car. You could leave the stock ones in and order that small shock setup for the motor to eliminate any torque lost to the motor rocking on its mounts. Personally I'd skip it completely and just go with the transmission mounts.
