I have a used Yamaha performance damper off of a G37 up for sale. I bought it a year ago for a project to add the performance chassis dampers from the Nismo to the standard Z.
I found the Nismo parts off a wrecked Nismo so I didn't need this damper.
This isn't exactly the same length as the 370 chassis dampers and has no brackets, so some fab work would be needed, finding Nismo brackets would help. It took me 3 years to find the actual Nismo parts, they are hard to find.
Hopefully someone can make use of this!
