Eibach to produce Nismo Pro-Kit springs.
I am officially the proud owner of the only 370Z Nismo specific Eibach Pro-Kit springs in the world!!! And I have to say that the ride quality is vastly improved from stock.
For all you Eibach fans out there with Nismo’s, you will be happy to know that they will start production on these springs very soon… I will actually be going back to Eibach for final fitment testing of the production model. Also my stock Nismo springs are up for grabs for anyone interested... PM with offers =) |
Congrats!!
Now I'll see you tomorrow :hello: |
What kind of drop and what are the spring rates?
|
1" front and 0.5" rear, progressive... I like how it evens out the ride height front to back.
|
Nice!!
I will take some pics tomorrow at the meet. |
Can't wait to see these
|
Nice!!! I like my fairlady with a$$ up high

Here it is after installation... picture was taken at the SoCal Centrally Located Meet by Waizzz... and for those that will surely end up wondering... no they will not "settle" any lower than what you see... good springs installed properly will not settle.
|
Very Nice! I installed factory nismo suspension on my touring model and was not happy how high the front was so this is great. How is the stiffness compared to the nismo springs? Any Spring rate specs out yet or if it's under wraps stiffer or softer?

You have any better pics and up close ones too? |

The drop looked good in person, congrats again. |
looks good, Imperial! :tup:

Great looking drop. Not sure if it would matter with the Nismo alignment specs, but I was able to get my front end back in stock specs with the Eibachs.

Thanks to all for the compliments.

Another great picture by Waizzz... please ignore the road dust on my rear =P
|
my teins dropped my front an inch and my front camber is now at -1.6 degrees. just food for thought.
|
I wish these front springs had less drop in the front, or I might be all over them when available. 1" is a lot for the front....not for fender gap, but for alignment. And I'm not happy with any of the front camber kits I'm seeing out there.
I love that the rear is only a 0.5" drop though....that's perfect to me. I have regular Eibach right now, and the inside edge of the front tires are wearing really fast with a 0.9" front drop. I'm either selling these springs and raising the car up, or getting a front camber kit. Minor camber wear is fine, but severe camber wear is just stupid to me with what 19" tires cost. I'm still searching for the factory alignment specs...anyone got a link that can help? |
Nismo Eibach Springs
I purchased a 2010 Nismo and interested in lowering the car and have been told that the Tein S-Tech's are the way to go. However, I've always been a fan of Eibach and was happy to see your post. Can you provide an update for me? Is the kit available now? If so, where can I get it from? If not, when can we expect it to be on the market?

Nismo 370Z specific Eibach Pro-Kit performance springs on sale now on their website.
|
So these are specifically for the Nismo 370Z model?
|
Sweet...I might have to get these :tup:
|
WOOOOOOOOOOO! ive been waiting for these...
imperial: can you confirm that you dont need camber adjustments for the rear? just the front? FYI: part number for nismo is #63103.140; while regular z's are #6393.140 |
No alignment kits were use whatsoever on my vehicle during development and they managed to get it within the upper limits of stock alignment specifications.

Just called Eibach to find out what the spring rates are for the Nismo. And I'm not going to lie. The car looks good but Im going to pass on this.
The 370z is already well balanced out of the box I do not need it to induce understeer. The stock Nismo rates are F- 8.6 R- 9.3 The Eibach rates for the normal Z F- 8.6 F- 9.5 The Eibach Nismo Rates are F- 9.8kg R- 9.5 which is a 14% increase in the front and 2% increase in the rear. I dont see why they would set this car up like this. They completely switched up the spring rate bias from front to rear. And a front heavy spring like that will not only induce understeer, but the valving range of the shock is also slightly altered, the rear rates being extremely close to stock, and then the front rates are more sprung. Even though it is within the valving range of the shocks, if Nismo really did a good job fine tuning their shocks then these springs will throw off the original feel Nismo was going for. Just to show you the rest of the spring rates Tein s-tech - F- 8.5 R- 9.4 Tanabe NF F- 5.9 R- 6.8 Tanabe GF F- 8.8 R- 9.1 Swift Spec R F- 10 R-10.5 So just about every spring manufacturer out there pretty much decreases the rates of our nismo which pretty much completely dtunes our upgraded shocks. Eibach although stiffer, went in a weird direction with their spring rates, and will alter the handling characteristics of the Z Swift is the only one by numbers is a performance option for our Nismo shocks. these are all converted to kg/mm if you guys want me to post it up in pounds per inch I can do that later. |

Final fitting at Eibach.

would this be feasible...mixing springs? the spring rates should be identical going from the above post. my goal is to just even the wheel gap...because currently, the front definitely looks higher than the rear of the car. edit: nevermind...it looks like the nismo springs are linear...mixing progressive in the front, and linear in the rear would likely not work very well. |
I found the Nismo springs did not lower the car at all. So the drop of the normal Eibach springs would be on par with the Base Z's.
I'm glad I got the Swift Spec R's... |

Also, Z's rear end already has a good amount of rear end squat to it when the car accelerates. I have a feeling that the Eibach spring spring might make the rear squat more, since the rear rate is softer compared to front.
This may be one of the rearsons why the rear is stiffer than the front from the factory. |
from the factory the nismo came with stiff suspension, period......
the rear end does NOT squat at all! it couldnt hurt to have a bit softer spring back there. look at what robispec did with the KW3s he runs. if im not mistaken he even removed his rear sway bar to help gain some give in the rear. |
The Z does squat. Just because you do not feel does not mean it doesn't.
It's funny how you brought up robispecs car because Sway bars have no effect on rear squat. With all the aero he has in the front maybe he was trying to induce a little more understeer. But look at his spring rates. He runs 8kg in the front and 10kg in the rear, without a rear sway bar. The main vehicle you should be looking at though is Paul Dentice. AEperformance 370z. The car is stock no aero with jic coilovers and a big brake kit. Consistently dominating the timeattack scene and his front to rear spring rate bias is pretty big, if Im not mistaken it was like 14 in the rear and 10 in the front. This car beat out Robi's 370z, and the AEPeroformance 370Z is pretty much bone stock. You also have to understand that even with these big spring rates it does not mean its really stiff. The rear of our cars has a pretty extreme motion ratio because the rear spring is seperated from the shock. This is one of the reasons why the rear spring is raked up so high. |

omg yes 1/2" of squat is still squat yes, but there is VERY lil squat. i never said the sways had anything to do with squat. i was just saying how he loosened up his rear end and what not. also do you own a nismo or a tourning edition? |
^by what he said I mean Im agreeing with s30Z (LOL)
Damn Fuct you fast! And also dont forget that our fronts are double wishbone too, so the spring rates do tend to feel much softer compared to other cars with McPherson type suspension. |
