Engine mounts 997
Discussion
Another update on the FF engine mounts, now completed about 900 miles, all the resonance has again reduced significantly at 3-4k, If I hold the gear and don't accelerate through there is a dull harmonic you can feel transmitting into the shell, as you go through this rpm, it feels a little more visceral than a stock car and I'm not sure I want it to disappear with more miles, I actually quite like it. It reminds me I have a tight transmission and it feels very connected
Overall very happy with the FF mounts

Not true in this case (and in many)
997 375 049 07 is for a targa or cab
997 375 049 08 is for a coupe
07 will be softer
The final two digits 000-000-000-xx997 375 049 07 is for a targa or cab
997 375 049 08 is for a coupe
07 will be softer
These are known as the “modification number”. For the most part, Porsche produced parts end in a pair of zeros. When you see something other than these two zeros it means there has been a modification to the piece from its original production run. This could me a minor change in the material specification, or even a significant change in the exterior dimensions of the part. Either way, each subsequent modification will receive a new part number with an incrementally higher modification digit. Often, these modifications are completed before the part is even installed on a production-line automobile; however, occasionally there are super sessions that will replace an earlier number.

Interesting I think there are a few rubber choices and different part number the normal mount is 997.375.049.08, I think there is .07 version, not sure how many more versions tbh
Generally with Porsche part numbers the versions should be interchangeable. And once a part is now on version 2 they will stop making version 1. So generally no real difference - in terms of interchangeability. There must be a difference but maybe it could be manufacturing changes or supplier changes. I made a few edits to my previous and added bold to highlight these.
Going back to the above example the first version should have been 00. Then 01 etc.
Now obviously this could have all changed but this is as I understood it. I recently saw reference to this elsewhere and remembered this topic so I came back to it.
It is my belief that the last 2 digits are the version number. Nothing else.
A new version supersedes the old version. Porsche are now selling version 08 and it can be used in place of all others.

The GT3's have there own mounts
If the GT3 do have their own mounts and they look the same externally then I'd guess maybe they are stiffer or something like that internally and could be a potential upgrade for the vanilla cars looking to firm things up. They look similar in the pics above but we can only see the top half.ATM said:

C2 price is £292GT3 price is £536 ...
That's either weapons grade price gouging, Porsche levels of supertax, or they might just be different ...
The FF mounts now have 1,200 miles on them and the slight resonance at 3.2k and 3.8k is lower again, you can feel a very small amount but it's very nearly gone. As I say I was happy with it by 900 miles and it's less and different, I think it's better without the slight resonance but it really wasn't a problem and I quite liked it from time to time.
