||Nismo in all of the control arms, ES for the subframe and diff. KYB AGX and Eibach springs.
The ride is excellent, especially with the shocks set to full soft, but there is noticeably more diff whine in reverse and under decel than before. Pretty sure it's from either the ES subframe or diff bushings.
Although it's noticeable, it's tolerable enough that paying through the nose for Nismo diff bushings is pretty far down the list for my Z budget :)
