STI vs SPT Group N Mounts

Post by Dynamic Entry » Sun Oct 21, 2012 6:26 am

Purchased my first set of Group N mounts in 2008, and from what I remember they were only available from limited sources.

I bought from Rallispec, upon recommendation of board members and was completely satisfied.

I recently bought another set while doing my transmission swap. This time I noticed that many vendors, including eBay vendors etcetera, are selling Group N mounts.

When I asked Rallispec about the mounts and the market, I got a next-day response that was personal and thorough. I again chose Rallispec, despite a slightly higher price, because of their response.

Subaru of America now sells upgraded mounts under their SPT brand and therefore anyone can purchase these through any dealer. Thus there are many places you can buy them from. However, SPT uses a different part numbering system from STI and many times we have found that STI has re-engineered the product to suit the US market or to avoid litigation concerns (they know that everyone sues everyone in the US!). In the case of the mounts its unclear if they are exactly the same as the STI Group N ones or not. No one has really tested them against each other. But other shops are selling them as STI Group N regardless. If you get a mount with an STI label and a part number that starts with "ST" you have a genuine STI part. If the label is a Subaru label and does not start with "ST" then its an SPT part.

We have and continue to buy our parts directly from Japan so we only sell genuine STI parts....not rebranded SPT ones.

Although Rallispec acknowledges that they are merely unsure if the parts are the same, I appreciate their concern and am happy to support their efforts to ensure they sell legitimate Group N parts.

Here are the mounts I received from Rallispec. Clockwise from top-left: 5MT Transmission Mount, Pitchstop Dogbone, RH Motor Mount, LH Motormount

Hmm hadn't heard of that. I bet they're the same is so close the difference is probably unnoticeable. I got all my sti group n mounts from nasioc slightly used at significantly lower prices than rallispec and I'm glad I did.

All of my Group N mounts have always came in Subaru packaging with Subaru part numbers no matter which vendor I bought them from. None of them have ever said STi on them. But then again I haven't purchased any in a couple of years so maybe they changed things?

I would be surprised if there is actually a difference. I suppose I could ask Subarugenuineparts since they sell the group n stuff.

My "Group N" dog bone has sti stamped on it, but the packaging for my tranny and engine mounts had no special marking.

I think retail for the tranny and engine mounts is around $210. I scored a set BNIB for around $120 on nasioc.
