hey guys, im in the process of getting d-specs for my car, im picking up a set of the revised oem z springs, and i dont know whether to get the dsp7 or dsp9. i searched and people say with z springs the dsp9 is the way to go because of the shorter z spring, but i see sedan owners with oem z springs paired with the dsp7. any input will be helpful, thaks

 

I'm not sure, but I think everyone goes with DSP 9.

 

I used the D-Spec for the 350z paired with my 350z springs because of the shorter length.

 

I have 05 Z springs with DSP 7s and it works great.
