More important questions: Are the dampers effective at dampening engine rotation, and does this really do anything to improve drivability or performance?

I had engine torque dampers in my RX-7. There it was helpful since the car had original engine mounts. Shifting was tighter without as much engine movement under hard throttle. Not sure about the Z though.

This is from Z1 Performance website, and this particular damper is the best made for the Z imho...but either way this pretty much sums it up well:

Ingalls Stiffy Engine Torque Damper 350Z


A self-contained elastomeric shock that mounts on brackets between the engine and the chassis. It reduces extreme engine movement and dampens the motion, providing many benefits. The “Stiffy” was originally intended for the sport compact market, but can be used for some Hot Rod applications if it is applied correctly.

Benefits

Greatly improved off-the-line acceleration
Reduced wheel hop
Improved vehicle stability
Reduced shock loads on driveline components
Smoother shifting
Reduced wear on exhaust system joints
Less vibration transmission to the driver compared to polyurethane motor mounts.
Less shock load, compared to torque straps and chains.
Drifting – helps reduce shock loads when wheels gain traction.
Reduces motor movement – decreases the chance of motor parts rubbing against
the hood and frame.

The Stillen instructions are sufficient enough once you have the parts in front of you and you are standing in front of the car. I speak from experience as I installed this piece on my own personal car back in '04 or'05.

My unbiased review is that the only noticeable difference that I saw after installation of the Stillen damper was reduced wheel hop, that is about it. I have since sold it and instead have opted for solid motor mounts (obviously a much more involved install compared to any of the engine dampers on the market). Would I personally purchase the engine damper again for my own car? No, but that is me (main reason being I'm not a fan of the aesthetics of a damper in my engine bay as I find my eyes are drawn to it each time I'm looking in the engine bay).

The Ingalls unit posted above looks to be a better (and pricier) unit than the Stillen and thus far we have not heard anything negative from the customers who have purchased one from us.
