For TEIN full-length adjustable shock absorbers installed onto NISSAN FAIRLADY Z33/ SKYLINE (CPV35), you can not reach the click on top of the shaft top with the click tool because of the original rear performance/ tower bar. So the rear damping force can not be adjusted with the click tool.

It is possible to use a long hexagon wrench to adjust the damping force through the hole in the original performance/ tower bar. But because the rod top is not directly below the hole, this process is very troublesome to perform.

Because of this, if you have TEIN full-length adjustable shock absorbers installed on your NISSAN FAIRLADY Z33/ SKYLINE (CPV35), we recommend using the EDFC, sold separately. (When installing the EDFC, the hole in the performance/ tower bar needs to be slightly enlarged.)
