EXACTLY what i was getting at with locating the motor!!!
Thank's for explaining it better Stazi.

What are you saying here, i don't follow?
I'm saying that the rubber is gone: that is, there's nothing between the bolt and housing but air, and a few scraps of rubber.
As for the excessive NVH: it's possible to have it be much worse if it's installed wrong. I had it preloaded badly the first time, and I thought I was going to tear the mount off. After loosening the tension on the mount, the vibration calmed down a lot.

I understand what you're saying, you are refering to a condition that appears only in worn pre-98 mounts....post 98 mounts are of different construction and are not suseptable to this issue.
If i can get time i'll snap some pics if you're not with me here...

if you want a softer mount then just buy a new stock mount. pole makes them harder shore for performance purposes

Is there a way to check this? Or how would you recommend installing them (info for the masses!)?
I personally just used a jack lifted just enough under the back of the tranny to ensure that its weight would be supported when I removed the mount. Do not use the jack to lift the tranny up, but it should be extended up enough so that the transmission/motor doesnt move when the mount is removed. Correct or not so much?
FWIW, my NVH increased quite a bit, but nothing that I couldnt get used to. I really never notice now, until I take a ride in someone elses 'tour and Im like "dang this is smooth!" LOL.
It all boils down to what your willing to live with vs. performance benefits. If you never launch your car or dont know what wheelhop is, this isnt for you. Though if your willing to sacrifice a little vibration for no wheelhop, go for it. I dont launch my car that much (no money for a diff), but when I do, its so nice now not to have the horrible shakedown of wheelhop like I used to get. The NVH isnt anything you cant live with.

There's more than one way to skin a cat. I think a lot of people would go for a mount that is stiffer than stock but not as stiff as these ones. And besides, if it was all about performance, why not make solid mounts out of aluminum?

how about a completely solid rubber mount would that be better than stock but not as harsh as the urethane. all my previous cars have had solid rubber mounts. is that why the contour feels so jerky between shifts? the front mount is almost hollow and the rear one has lots of holes in it. whats the deal with that? i like the way by frineds 96 maxima feels. i can shift it so fast and smooth that it feels like an automatic. it seems like most american cars that i drove and were stick are jerky. my girls cavalier is the worst i hate driving her car. i realy hate having to shift slow so my car wont jerk , i have new mounts and the insert on the front mount.

The way I see it, I dont think you have a choice. You may REQUIRE it. But youre in a different boat than most.
OK, maybe not require, but you may find benefit in having it with the amount of hp/tq you'll be putting out when its all said and done. 
Well... I see it the same way you do. How about that? That quote was directed towards daily drivers. The mods I'm making to my 99 SVT definitely put me on the radical fringe horsepower-wise and I�ll be making all kinds of NVH compromises both there and in the suspension. Of course I�m interested in poly filled mounts and I hope Pole120 is still making them.
But that is not going to be my daily driver!
SVTs can be sporty and handle great without vibrating the crap out of everything in them. IMHO NVH is just as important a part of a balanced daily driven sporty car as power and handling. The car should be a pleasure to drive in all respects ââ?¬â?? at least if Iââ?¬â?¢m going to drive it every day!
Maybe its just a matter of taste and maturity.

I drive mine everyday and I didnt experience much more rattling than before. My car never really rattled anyway. But it is a comprimise. BTW Stazi, I think you just scared away about 20 people from SZ06 for making the teabagging and soap in a sock comment.  -tropictour
