Could anyone tell me what the advantage is of upgrading the stock wrx transmission mount to an STi group N transmission mout?

Yes, it reduces the movement and shuntiness when coming on/off throttle by making the mount stiffer, of course that also means more NVH!

Thanks for that, its just an upgrade ive been considerin along with the STi engine mounts to stop the slight wiggle in the engine bay, not to sound like too much of a noob but what do you mean by NVH?

Noise, vibration, and harshness (NVH), also known as noise and vibration (N&V), is the study and modification of the noise and vibration characteristics of vehicles, particularly cars and trucks. While noise and vibration can be readily measured, Harshness is a subjective quality, and is measured either via "jury" evaluations, or with analytical tools that provide results reflecting human subjective impressions. These latter tools belong to the field known as "psychoacoustics."
Interior NVH deals with noise and vibration experienced by the occupants of the cabin, while exterior NVH is largely concerned with the noise radiated by the vehicle, and includes drive-by noise testing.

Top man!!!
