I've tried and tried and tried again to search through here for some information, and can't seem to find an answer. I've seen the question asked several times, but again, never an answer!

I recently picked up my second G-Sedan, a 2007 Journey package. I'd like to set her down a bit, around 2". I noticed that the spring rates for the 2007 350z tend to be quite a bit higher than the respective coupes, and even higher than the sedans.

I remember from my V35 that the Z springs would add 1" to the advertised drop, and coupe springs would add .5" to the advertised drop. Does this hold true across the V36 chassis? Are the springs even still compatible across platforms?
