Did you do a before and after measurement on the drop?
What are your current alignment specs?
Thanks!

i got RSRs for the Z on my G a few weeks ago (thanks to street image)... springs settled a bit after a while, came out with about a one and a quarter finger gap all around.
scrapes a lot, drives me kinda nuts... but I love the way it looks.

Good question.
I too am in the market for springs and was also curious about the difference.
Are the Z springs also stiffer than the springs made for the G? I'm weary about putting Z springs on because it should be designed for the weight distribution of the Z? right?

Here are the spring rates in comparision to all known lowering spring/coilover product made for the Z33/CPV35/V35. If a product is not listed, that maker refused to give out the info.

As you might notice, the Tein H-Techs for the 350Z add the least amount of additional understeer (w/o adding to oversteer) keep the springs rates closest to stock, allow a 0.8" drop in the front and a 0.7" drop in the back for a G35 and a drop of 0.3" in the front and 0.2" drop in the back for a 350Z. They also should not wear out the stock shocks too fast as the spring rates are mildly more stiff than stock, yet you get a nice subtile drop. By adding them I'm hoping to stay within the stock camber and toe ranges, thus not having to add camber/control arms and toe bolts...

about two months ago, i installed tanabe GF210 made for the Z. it's looks great and the spring rate is just what i wanted--stiffer than stock. the drop is about 1.5" even though it says 1" on the box.
here are some pics:
