i KNOW its been discussed before but for days of searching my3z.com and various vender sites i cant find it.
i want a lowering spring that has a stiffer rate than stock and will lower the car around and inch give or take a little all around.
so far all i could find is the rsr springs are a stiffer rate i think but only lower it about .5 of an inch, tanabe's gf210 seems to be a bit stiffer than stock but im not sure of the quality of spring it is.

You really need to replace your oem 03 shocks are part of the package.

IMO, trade some drop height and run Tein S-tech. If your ok with a progressive spring, I'd go with Eibach Pro-kit vs GF210 because of the higher peak rates on the prokit (avoid the sportline or anything that has that much rate spread betwenn initial and final)

Your oem spring rates for a 2003 Z are
314/342

Eibach 350Z progressive springs 1”/1”

The whiteline springs look really good on paper. Anyone have experience with these? Specifically on an 04.5+?
