I put RSS mounts in my car and love them, but I do think if you're not trying to effect a handling change of some sort then it's best to stick to OEM stuff.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Lets talk engine mounts. I'm due to change mine and i'm reading alot different things about aftermarket and stock ones.
What mount do you guys have and why?
Looked at the RSS Engine Mounts for mine but hesitant in changing something which is still working fine. In the Porsche forums around, there is about a 50/50 chance you will like them or hate them. Main complaint is cabin vibration.
Do engine and tranny mounts at the same time. Not sure if any different than a 996tt, but i did lots of research. Stick to factory assuming they fit. E.g. 997 tranny mounts and 964 rs semi solid engine mounts with specific factory bolts nuts and washers that need to be installed in certain order.
Why, I reckon factory engineers have bigger budgets and Porsche have better QA in manufacturing that any after market suppliers. Tried and proven on a shed load more cars than any after market supplier. Heard poly bushes are very stiff and transmit a bit of vibration through the drivetrain. Poly aint exactly a new material and would of thought if Porsche saw value in it it would be on a 997. I want something a bit stiffer than stock but not solid. Hence 964rs semi solid. Two 996tt tuners I spoke to recommended forget aftermarket and run with those factory mounts.

, I've got a pair of brand new engine mounts for sale
here
. (OEM?) Porsche, bought them but never get to get them installed. Only thing is I'm in New Zealand so shipping cost could be a factor although I haven't actually checked.
I replaced mine with stock OEM, felt no need on a road car to go with anything different. I'm also very happy with the stock Bilstein's and bushings, maybe a I just don't know any different.
There can be NHV from semi-solid engine mounts, one engine builder in the US says the extra vibration can lead to the knock sensors going off.
There are two main brands from the US that are the most popular: RSS and WEVO
FunctionFirst also offer a semi-solid engine mount where they inject a mould into standard engine mounts to give a true "semi-solid" feel.
Transmission mount on the 996 is difficult to do - not even PCM wanted to do mine for me without dropping the trans even then they said no one there had ever done one. I'm planning on installing the transmission inserts - haven't decided which brand yet.

buy me lunch and ill help you swap them out
So my lovely mechanic at Wessiach in melbourne did awhole lot of work for me last week. Started with a new exhaust Tubi Style "R" for the 996 but more interestingly was the engine mounts.
Both engine mounts had completely failed. By failed i mean the rubbers had been stretched 2inchs or more from the where they were supposed to be. When we put the new ones in, the engine mount bolt didnt make it through all the way, so we had to jack the engine up 2 or so more inches to get it to stud through so we can put the bolt on.
I ended up using the 996 turbo mount which are a direct fit but give a more firm feel than the stock one. Doing this has improved the following.
1 - Clutch pedal feels lighter... A LOT lighter thank god..
2 - Shifting between gears is so much smoother but i have a short shift and its a little notchyh. (i dont like it)
3 - The rear end of the car feels so much more firmer and controllable.
Well worth the semi upgrade!!! it's made my car feel alot smoother in the drive train area!.
I put RSS mounts in my car and love them, but I do think if you're not trying to effect a handling change of some sort then it's best to stick to OEM stuff. No perceptible change to NVH but my car does lots of NVHs in the first place so...
Hey Jim,
I ordered these:

The delivery was super fast and they stock parts. even my mechanic was amazed at the price.
Well worth doing the engine mounts, it's made the car less... wobbly at the rear.
