Bilstein damer kit with old/new OEM parts.
The existing OEM ones were tired and not getting back to free length state quickly enough. Good idea to replace it now.
The gas/oil chamber is probably blown.




Quite obvious the difference between the new and old parts. The rod bushes were completely compressed.
I always recommend replacing these parts to new ones.




Lower perch selected and as this NSX uses wheel spacer with unknown alignment setup, I will adjust the direction of the spring seat later. For now, I’ll put the lowest point at this angle.




Cleaned the spring briefly before the installation.




Not sure why Bilstein sends the rear damper with bottom side of dust cover open.
At the front, they use the dust cover that will seal against the damper body but not at the rear.
Despite this fact, they still supply the tie-wrap in the kit.

There are several different view on whether the dust cover should be sealed or not but considering the street driving usage, I normally seal it any way. It’s easy to cut the tywrap later if the owner doesn’t like it.






After treating the damper rod top section, placed back the cap.
Will torque the mounting nuts later under 1G.


Hope to fire up the engine soon.

    Hi Kaz, I'm thinking about changing to lower perch settings on my Bilsteins too. Don't remember now but is that ring a spring-like? Meaning you just extend and move it to the lower groove? Thanks

    If you are referring to the locking fastener that is inserted in the groove of the damper body to hold the spring perch, then it’s a C-ring design.
    You should be able to catch the opening of the C-ring in this photo.



    If using the lower perch, please make sure to double check the clearance around the perch, spring, tyre, etc.
    You should loosen all of the bush related bolts/nuts including the one at the control arm, forward lower A-arm, etc while at the alignment platform as you are changing the ride height.
    With the effect of the lever ratio, changes at the spring perch will be multiplied for the actual ride height.
