All four. Same as on the Nismo z. I must be wrong but it seemed to lower the car 1/2 inch. Used for 3 weekends before the rules changed. Nice upgrade if you still want some comfort. I'm told the fronts are 492. The rears are progressive. I'm told 336-672.

SOLD

These pictures show ride height, as well as how much could lean if you have slicks and stock sway bars.

 

can you show a picture of the springs installed?(to see how much the drop is) and where are you located in south florida?

Thank you in advance.

 

are these s-tune or off of a nismo Z?

 

it looks like you wrote nismo on the springs with a marker

 

yeah you got a point.

 

probably did to keep his parts straight. I write on my parts too. The last thing id want is my E34 springs ending up in my Z haha.

also, is the $150 shipped? are you doing local only? if shipping not included how much to 07470? Thanks!

 

Ha! Burgandybaby is right. I didn't buy springs and write Nismo on them hoping to fool anyone The tags from Nissan are still on some of the springs if not all of them - if that helps. I'll put some pics of the car with the springs tonight so you all can see ride height as well as how much lean in the cormers (though it was with stock swaybars...)

These are springs like off a NIsmo Z.

I'm in Plantation in case anyone wants to pick them up. If you do, you are welcome to rumage through my other crap...

Shipping to NJ is $20.

Thanks,
Bill

 

I am interested in these as well after pictures are posted. I am in 30022 or I could have my dad swing by and get them. Thanks!

 

PM me with any other Z parts you have up for sale. I am local.

 

correct me if im wrong but springs from a Nismo Z do not lower the car

 

Oem springs off of a Nismo Z do not lower the car. And they are far too stiff to run with any aftermarket shock other then perhaps TcKline DA's (ironically the front rate is too soft since the shock was designed for a 690lbs front spring).

Nismo Z (2007-2008) ride height is the same as other Z models linear front, progressive rear (initial and final rates shown)
492/336-672

OTS Koni yellows can handle the front spring rate, but not the rear rate.


So, unless your planning on sporting some revalved koni shocks, these springs really do not have a market sorry to say.

 

Dude I was going to go off because your statements didn't add up for me. Instead, I will ask you to clarify what you mean. Are the Nismo Z shocks so special that no aftermarket shock can improve on it or even duplicate it? The balance of these springs was excellent on the road course, and they were soft enough I wouldn't mind driving it on the street - I guess that makes sense since the Nismo Z is quite driveable. Seriously I would like to learn what you know and I think it's great to share this knowledge with anyone that might be looking for reasonably priced spring options. Please explain further.

i don't see why these wouldn't go well with most aftermarket shocks, just won't lower the car any

 

I thought I was pretty clear, but I'll have another go at it.

2007-2008 oem Nismo Z springs have the following spring rates
492/336-672 (rear are progressive initial rate is 336lbs, peak rate is 672lbs.

No aftermarket shock can cover those rates front and rear other then oem 2007-2008 Nismo shocks.

Koni will argue that their shock can. No it cannot, I've run that shock with a variety of rates and have run then on a shock dyno. Even a 492lbs front rate is a streach. At the very least you'll need to revalve the rear shocks.

Tokico D-specs are valved to cover up to a 450lbs rate per their own tech, though one person here that I trust did dyno them and feels they can handle up to a 535lbs rear rate. But remember, we're talking about 692lbs rear springs.

Tokico HP and KYB GR-2 are out without question.

That leaves TcKline DA shocks. They are valved for 690/690 springs, fine for the rear, but undersprung with a 492lbs front spring.

So, without the oem Nismo shocks that are valved to run them, selling the springs, which do not lower a regular 350Z will have a really limited market.

Not trying to kill your sale, I'm just doing what I have alway's done for this community. Give them info to make more informed choices.

 

Off topic, but my question is how did the Corolla end up in the same run group?

 

In SCCA, ther are 5 groups. 2 are taken by open wheel cars. SCCA usually tries to put the production cars (actually highly modified older cars) into their own group. From SSC (the car you see in the pic), to Gt1 race cars, we only have 2 groups to fit into. I prefer to be with the slower cars....

In regards to GSedan35 comments, he has valid data. I think it is silly to think you need to have shocks designed for both ends of the progressive rate spring, but other than that I think he is right. So, who would want these springs? Someone who drives daily, and occasionally does an autox or track day. For that person, you want a softer spring and shock for daily driving and when you have the girlfiend with you, and yet you want performance at the track.
I'm suggesting that not only is there an aftermarket shock that will work with these springs, but ANY aftermarket shock will work with these springs for that purpose. These springs are extremely well balanced for the car. They will work fine with your stock shocks. If you go with aftermarket shocks you can dial down the damping for daily driving, and crank it up when you want performance. This combination is actually what many stock based autox and roadracing classes do.
So, I looked at the prices of other spring choices. Even though I would pay $150 in a heartbeat for these if I was using my Z as above, I've dropped the price to $100. I will also guarantee them. If you are currently on stock springs and you put these in, and you are not happy with them, I will pay for return shipping. So I'm betting return shipping that you will be happy with them.

PS, Though GSedan35 may have cost me a sale, I can appreciate the info sharing with the comunity. No hard feelings. However, If GSedan35 or anyone close to him tries to buy these springs after that comment I will refuse sale. I beleive he was doing the community a service by sharing info, but I don't want to encourage the tactic as a way to reduce price and competition.

Cheers,
Bill

 

The only shock you can unbox and successfully run with the springs your selling are the oem Nismo shocks.

You cannot adjust into a control range what will work with Koni Yellows, D-specs, TcKline or even Truechoice Phase II, III, or IV. None of them can handle the rear springs peak rate.

Just to say it, here is where your springs have value.

Owner doesn't want to lower the car, but wants a stiffer front spring. He already has or will purchase Koni's or D-spec shocks

Nismo front springs, oem 2004.5+ rear springs on Koni or Tokico D-spec shocks
492lbs/427lbs

And to explain something else behind what I say. I have run and tested more setups on this platform then anyone I know. I've also run a lot of those dampers on the shock dyno. So, I'm not guessing on this.

 

Is the peak rear spring force the force the spring exerts in a fully compressed state that it would see in the car? In initial is level of compression steady state in the car? Or are those numbers just spring rate from free to fully compressed?

Either way, you still have a fundamental mistake to think the peak rate is what you design for. Why did you do that?

 

I'll take em. Let me know what the shipping is 98208 and I'll paypal you the funds.
