Yamaha body dampers and Nismo body brace sets questions
 

Yamaha dampers and 3pcs nismo body braces do they bolt on to the same locations or no?

Yes, if you have all of the mounting hardware (bolts and brackets) they mount up to OEM locations

If you have a 25 or bigger oil cooler. The front dampener needs to be flipped (the dampener end needs to be on the right side), and a 1/4" spacer under the mounts to give you enough clearance on the oil cooler.

Has anyone actually installed them vs not having them and noticed a difference? From what I gather they are just a comfort feature to tune out chassis harmonics but I really haven't felt any odd harmonics or noises/rattles through the chassis at all to justify it.
