I need a little clarification help --- so, there are TWO SETS of NISMO springs available?? IE - "NISMO S-tune" springs, and then NISMO OEM, which I'm assuming are what is stock on a NISMO 370z off the showroom floor?

would anyone have a comparison between the two NISMO springs, for height (of actual springs), spring rates and finishing ride height??

I'm a bit confused on which is which at this point, in regards to what might drop a 370z base
