A little drop to me would be Tein 350Z H-techs, S-techs, Hotchkis, RSR or Swift (not the spec-R)

Define the drop amount in numbers that your after as in a min and max.

In case this helps here's a master list of springs and specs.

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

Swift 350Z linear springs .8”/.6”
Spring rates in LBS 336/364

Swift 350Z Spec-R progressive springs 1.2”/1”
Spring rates in LBS intial/final Front: 291/392 Rear: 280/448

Nismo T2 350Z Linear springs 1”/1”
Spring rates in LBS 625/700
Way too much spring for oem shocks or Tokico D-specs, HP, GR2 or Bilstein Sport(unless revalved). Koni sports are debateable.

Vogtland 350z progressive springs 1”/1”
Spring rates in LBS initial/final front 257/354 initial/final rear 285/422

DR21 super sport 15mm drop

I had eibach prokit springs and i hated the performance so i got Kbee coilover and am now happy with the looks and added performance. Coilovers are a bit pricey but I'm of the opinion that modifying a car should not only be for looks but also involve improved functionality

if i had garage and tools, i probably try to do myself.
since i got nothing so i took it to shop.
they charged me 200 ~ 300 between there i forgot.
but it's better u study before you go. and watch them if they do right.
this guy forgot to install my camber TOE BOLT.

thanks to one of 350z member's tread!

- alignment took it to firestone, other alignment shop couldn't do it, ( they said my car was too low.
