Here are all your choice's in the market for a less then 1" drop

S-techs, Hotchkis, RSR and Swift would get my vote.



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

Tein H-tech 350z linear springs .3”/.2”
Spring rates in LBS 358/375
Note: in actuall use stiffness on the car didn't quite match the specs that Tein say's the springs deliver, thats IMO of course.

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

RSR 350Z linear springs .6”/.6”
Spring rates in LBS 345/417
Note: Can be difficult to buy, contact vendor or manufactuer directly first.

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

Kg/mm springs 350Z
DR21 super sport 15mm drop
Spring rates in lbs initial/final front 246/398 initial/final rear 252/409

Espelir 350Z progressive springs 10mm drop or .4”/.4”
Spring rates 386/515 (softer initial rates are unknown)
