Very cool Bill, I likes it.
On your year model will this cause damage over time without dampening of some kind?
Anyway I know what you mean about power to the wheels fast, because when Jake put his "special" mount in my car it was a day and night difference. Lay rubber for all of us!

I gave Paul a couple high-durometer thick washers for his 2k. These will go on the OUTSIDE, just under the bolt head and nut. They won't flex much (1/8" max under load) but will damp out alot of vibration, especially at low RPM'*. I had a couple scraps laying around.
It'll be interesting to see how my washers work, and how he likes the change when he gets home on his own car.
Bottom line is YES, you can dampen out some of the vibrations without inducing more flex.

Yup. One for the top and bottom. The bolt and nut don't touch the steel halves of the mount that way. They are isolated/insulated with elastomeric material.
For mine, I'm unsulating/isolating where the bolts for the trans and subframe meet the mount instead. Different location, same effect.

Paul nailed my camera.
Then he went into inspection mode:
We found a bit 'o rubber. Wonder where that came from?
Before we put the washers in, we found a small stress crack:
Marked the bolts and washers to make sure they don't shift over time (before testing):
After we tested it, we realized Paul broke it. Why? Not enough reinforcement. We've discussed future plans.
The mount needs to be stiffer, but the vibration damping definitely took out about half the vibration in the steering wheel. That part worked, but the mount itself needs to be much stronger:
We'll drink a few somethings or other and talk about it some more.

Hahaha, do you have a cutout for open "headers"? 
Anyway, it looks like the engine is still moving a decent amount. Did it move less before the washers?
