Read that their stiffness rating is between Group N and stock WRX mounts, so it should make a slight difference.

They are the same PN. I have had all three side by side including US wagon mounts. The only difference is between the Group N and all the rest, and the US wagon tranny mount has slightly less material than the sedan/STi.

SPEC C mounts are the harder ones.....the WRX and the STi ones seem to have the same amount of flex. The SPEC C ones are noticeably stiffer....I have an even harder set from a JDM auto trannied car....they are super stiff

There are group N mounts and all the rest.

That is all.

This has been discussed at length and has gone all the way up the chain to SOA.....and there is group N and the rest...as in the rest are ALL the same and the group N are stiffer (higher duromer) material.

As far as anyone knows, the group N mounts were NEVER a factory stock part on ANY production Subaru vehicle, and must be added after production.
The P/N's are the same on some group N parts as the NON-group N parts because the same mold is used to produce both parts, and THAT is where some confusion comes from....but the difference in material is readilly apparent upon inspection.

Thanks a lot for the information. I did a search a while ago before posting this and became confused but now it is all clear.

...and the group N mounts(except the pitch stop, mebbe) are well worth the performance increase, if you are so inclined...they do add some NVH but in a well modded car, the extra won't be noticed much

Yeah, I would skip the pitch stop, I don't feel like it's done anything for me except look tough.
