Thanks for posting :tup:

BTW, allegedly a good rule of thumb is to keep the springs within about 10% of the original rate for whatever dampeners you have.

So, you can use that info to determine a good match to either the OEM or Nismo shocks.

Oh -- one question: Are those the rates for the S-tune or the factory Nismo?

They are one of the same my friend.

Really? I thought the S-tunes were different / even stiffer :confused:

Thanks for clarifying :tiphat:

On a related note, anyone know what the stock bumpstops are rated at?

Bump, anybody know?

Has anyone tested the rates on the black springs verses the red ones (pre 2015)?
