H-techs and Hotchkis would deliver the best ride. S-tech has more spring stiffness vs the others, and yet doesn't drop so much that your into the bumpstops too much more.

NF210's should be avoided, too much drop with zero increase in spring rate over oem to help maintain shock piston stoke (you'll be into the bumpstops far too often in normal regular everyday).

Oem spring rates

350Z 2003/2004
Front:314 Rear:342

350Z 2004.5 to 2008
Front:314 Rear:427


Eibach 350Z progressive springs 1”/1”
Spring rates in LBS initial/final front 296/384 initial/final rear 316/421

Eibach 350Z sportline progressive springs 1.2"/1.2"
F: 239/400 R: 257/435
Very wide spreads between the softer initial rates and firmer peak rates.

RSR 350Z linear springs .6”/.6”
Spring rates in LBS 345/417

Hotchkis 350Z Linear springs .6”/.8”
Spring rates in lbs 340/330

Tein S-tech 350Z springs .7“.6“ (fronts are slightly progressive, rears are linear)
Spring rates in LBS 386/402 (estimated front intial rate is 327lbs)

Tein H-tech 350z linear springs .3”/.2”
Spring rates in LBS 358/375

Progress Technology progressive springs 1.0”/1.0”
Spring rates in LBS 425/385 (final rates only, softer intial front progressive rate unknown)

Tokico D-spec shock & spring package
350Z - DSK512 - 375f/375r - Linear Springs 1"/1.5"

Tanabe GF210 Series 350Z progressive springs 1”/1.2”
Spring rates in LBS 336/375 (only peak rates are published, softer initial progressive rates unknown) Not much stiffer vs oem, IMO Eibach prokit is a better choice because of that springs higher spring rates which should help keep you off the bumpstops more often.

Tanabe NF210 Series 350Z progressive springs 1.2”/1.2” higher
Spring rates in LBS 314/353
Little to no increase in spring rate over oem, little to nothing added to keep you off the bumpstops

If he goes with either one, would he need the A arms for the front or would he still be within specs without it?

Gsedan, thanks for posting all the specs.

I had read on Hotchkis's soft ride but didn't know the rears were that much softer than '06 OEM springs. I was considering buying them as a part of their TVS Stage 1 kit but probably won't now.

I have the TVS kit on a 2006 350Z GT, and the car feels must "firmer" all around. It totally eliminated the "nose-dive" under very hard braking...and is still livable as a daily driver and good for track days...
