NISMO damper what is it doing

I have seen all the post but I cant find a real document about the damper function

I know what I think is is for, but after 3 years I still am not sure.

I think it dampens something??

Their job is to dampen vibrations and harmonics that are a natural byproduct of running stiffer springs and more aggressively valved shocks (and lower profile tires) as the NISMO Z comes with. I have the front one from the NISMO 350Z on my car (the rear wont fit due to my sub box). It is a completely dramatic change (for the better) vs not running it. My car was never uncomfortable, despite its very low stance and low profile tires (HKS coilovers and 265/30, 185/30 RE050A), but with the front damper installed, the car was a pleasure to drive on our crappy local roads. So much so that it is more composed than my daily driver ('07 9-3 Aero Wagon).

Here is a review from one of our Subaru STi customers who had them on his car (Yamaha makes them for Subaru, Nissan and I believe there are a couple Toyotas that have them too)

I've taken both of mine off and I can't tell a difference

inventor and yamaha explains..

Hello,

Check this site for the inventor and description.
Yamaha Motor USA - Yamaha Performance Damper

Thinking of adding to my 370z non nismo. Anybody have a stillen gen 3 CAI and 25+ row oil cooler? Does the front chassis stiffner get in the way a bit?

Body is always moving/vibrating when it is running. Never ending the vibrating
Mr. Sawai determined that if he could increase the decay rate of these vibrations inside of the structure, he could improve many elements of the vehicle. It took him only one year to take the concept of chassis damping from an idea into an actual working prototype.

Following a half year of testing, the first application of the PD came about in 2001 on the limited Toyota Crown Athlete VX with only 300 produced for the Japanese domestic market. Toyota decided to expand the use of the PD equipping select models globally with the Corolla XRS, Matrix SE and TS (in Europe). In 2004 another Japanese manufacturer bought into the performance damping concept with the introduction of the limited edition Subaru - S204. This proliferation of Yamaha technology in the automotive sector gained wide attention within the industry earning Yamaha several prestigious engineering awards in 2006 including

I got the G3's with the Z1 34 row cooler. I added a 1/4" spacer under the mounts and flipped the dampener around.

"Even if the car body is reinforced and made more rigid, road surface input through the tires and load shifts during cornering make the entire body act like a spring, causing the occurrence of micro vibrations. The performance damper acts to control the transmission of micro vibrations to the body. During circuit driving, micro vibrations from the car body are transmitted through the steering system to the driver, resulting too often in unnecessary steering corrections. With the performance damper installed, however these micro vibrations are eliminated and excessive steering wheel handling is no longer needed, resulting in more stable handling. Also, in normal driving, the micro vibrations are eliminated, as well providing a much more enjoyable and comfortable ride."
