I just bought a 2007 350z Nismo, its been lowered and the dealer told me that the previous owner just changed the spring. It's to low for my taste and I would like to have it like stock, here come my question. Does the nismo have the same spring as the normal Z? if not where can I buy the original nismo spring? any recomendation?

 

I believe the 350z Nismo has the S-tune suspension.That means,the springs on the stock Nismo will be a bit stiffer and the car would sit about a half a inch or so lower.The Nismo does ride harder than the other 350's.
Thus,the springs on the other 350Z's are different.
If you are planning on going back to the stock suspension,the previous owner may have changed more than the springs.The S-Tune suspension kit runs between$1,200-1,400.It includes shocks&springs.I imagine the springs for the
kit could be ordered seperately.Courtesy Nissan is a supplier.Or,just do a search for Nismo parts.

 

The only way to know for sure is to look at the suspension.

Please don't put standard OEM 350Z suspension on your Nismo. The main reason the Nismo is worth it imo is the suspension.

 

S-tune springs cannot be ordered seperate from the shocks.

Nismo Z springs should be something you could order from the Nissan parts department. PROVIDING you had 100% proof the parts ordered were Nismo Z and not from the regular Z



Nismo 350Z's do not have the Nismo S-tune suspension. Shocks and springs are totally different that that kit.

Nismo Z (2007-2008) ride height is the same as other Z models linear front, progressive rear (initial and final rates shown)

Nismo S-tune shock and spring setup 350Z (twin tube, fixed height)
.6"/.6" drop (drop spec published in Nismo catalog)
Spring rates 393*-448/254*-504
*estimated initial spring rates (notice the front doesn’t have much spread)


Notice the spring rates the Nismo Z uses. Pretty much every avaliable lowering spring on the market does not have spring rates that can work correctly with the cars oem shocks.

Most often purchased by owners chasing spring rate specs. But this spring is also often resold when they fail to deliver on the promise those specs were supposed to delivery. Not a bid surprise, they are progressive, not linear.

Thanks guys for your response, I'm going let the mechanic to tell me what type of spring does the car has right now, I'll let you know as soon as I know.
