Details
Factory mounts are much softer and are catered for the general public. Enthusiasts are always looking for an upgrade and these STI motor mounts are one solution.
The engineers at Subaru Tecnica International developed a new set of motor mounts with much harder rubber which will help deliver more power to the wheels. They're aimed at customers who compete or usually find themselves on spirited drivers more often than not.
STI vs Group N Mounts
In general STI mounts use a harder compound than stock OEM mounts, but are not as hard as Group N mounts

Perfect match for 2015+ WRX
By redhunter April 4, 2017Replaced my stock mounts with these and they are identical to the stock mounts (including the integrated spacer) except for the stiffer rubber. I had a Group N transmission mount already installed and there was zero increase in NVH even at idle. Since my drive train was pretty much locked down before I installed this, it's hard to tell how much improvement. There is, but the greatest benefit is likely spreading out the forces throughout the drive train.
