Spoon Engine Mounts - Liquid Filled like OEM?

Probably not, I'm sure the theory of it all is sound(haha puns) but I really didn't notice a change to the car other then the slight difference in how it feels throttling and shifting. Not any difference in sound to me. Everything feels nice and crisp, but without the vibration of urethane mounts or the sound that comes with them.

Stick with the OEM mounts. The engineers used hydromounts for a reason, to add system damping in the vertical direction.
The fluid you see is just a glycol blend. Stiffer mounts and/or the addition of an ETD will negatively impact NVH.
The S has a typical longitudinal (RWD) mount system which is designed to react to torque about the torque roll axis, in the vertical direction.
Adding an ETD messes with the balance and creates an over-determined system, it also adds an additional transfer path for vibrations.

I have Mugen mounts (of course 
). It took a few hundred miles to break in, but once broken in you can't tell much of a difference- aside from the increased performance. Like mentioned previously about the Spoon mounts, there is a slight vibration when sitting at a stop light and have the a/c blasting. The shifting is much more crisp. If you are upgrading mounts, Spoon or Mugen are the way to go.

A few hundred miles to break them in is fine. Crips shifting means the power train is much more stable (less movement). This is goooood

I just did my high flow cat last weekend and same thing but with the diff mounts - noticed one of the diff mounts was cracked. Been going back and forth on what to do - OEM and pony up for the Spoon mounts.
Innovative doesn't interest me at all. I had their 75a engine and trans mounts and hated all the NVH from it.

Many owners have uprated suspension with stiffer than oem spring rates,
engine&drivetrain mounts for torque movement ect is not the only movement involved

I also bought spoon diff mounts but haven't gotten around to putting them in. Now that the weather is getting crappy and I'll drive the car even less I'll probably put them in along with a few other bits I have been lazy about installing.

That's fine, but the original poster doesn't have spoon mounts or an ETD, to be objective in his claims. I have both, and drove both within a couple hours of one another, after driving the S with stock OEM mounts for months. My spoon mounts aren't even broken in yet. I was just sharing my real-world experience of swapping them and what I hear/feel.
Not trying to discredit what he's saying. I just, don't think it matters to the effect/gravity he has made it out to be, for the two products(spoon mounts and ETD) compared to OEM.

Bogus. An ETD literally is a tiny shock absorber fixed to an upper portion of the engine with the other end attached to chassis. ETD are much bigger in the fwd world because of super soft Oem mounts. Fluid filled mounts in general have that give and compress to allow movement under load which helps mitigate NVH. This in some circumstance can help produce sloppy shifting along with bucking. ETD gives support to the Oem style mount like a roll bar's impact on suspension. Having both the upgraded fluid filled (Mugen/spoon) mounts and ETD as @Deckoz does is likely overkill but still provides more compliance than solid mounts. Bottom line is the ETD is much cheaper but if you have a bad mount fix that don't try to solve a symptom of that by adding more hardware.

So the consensus is the spoon/mugen are fluid-filled? I was considering going with HardRace but I know those are solid rubber, even the street versions. My S2k isn't my daily but at the same time I made the mistake of going full Beatrush poly mounts in my STi and the car was just awful as a daily. Admittedly I didn't even give the mounts enough time to break-in before I swapped them out for the slightly stiffer than OEM Group N mounts, but regardless, poly mounts are hell, and anyone saying it isn't that bad is a maniac. I know we're not specifically talking poly mounts in this thread, but typically anything stiffer than OEM for driveline mounts really sucks....I'd never consider anything poly for the drivetrain in any of my cars, daily or weekend....That's why the playing field is a little small. To me it's only the Spoon, Mugen, or Hardrace mounts I'd consider....I think Ballade and Megan are in there too. Basically the same design as OEM just slightly stiffer RUBBER (not poly, thank god)
