What are body dampers?

MJB

Hey Jordo, not the best picture but I guess it will do. I took this while I was installing my new toe bolts. Anyways, the damper is located directly in front of the spring perch.


Off topic... I thought the Nismo did have more welds on the chassis. This came directly from an Edmunds article in 09

"Underneath its showy aero bits, the 2009 Nismo 370Z is no less hard-core than the 350Z Nismo. Autech still takes the standard Z-car chassis off the assembly line and welds the seams of the unit body by hand — a labor-intensive process that increases structural rigidity beyond that of a normal, spot-welded unibody. Mass dampers are then fitted between the unibody's left and right frame members to control the extra vibration inherent in a seam-welded chassis."

So has it been confirmed that only the 350 Nismo had the extra welds?
