Right lowering spring for 2013 Nismo
 

This is one of my first posts even thought I have been a member for some time so I appreciate your patience. After much time spent researching I really just need a simple, clear answer and I'm am more confused that informed, so I have created THIS thread.

There are SO many options for the 2013 Nismo and I am trying to determine if Eibach Pro-Kit, Tein S-Tech, Swift Spec-R or H&R is the best choice for a spring to lower the car. I plan to use the Nismo performance dampers so we are only talking lowering the car.

As I understand it the Eibach Pro-Kit lowers the front -1.0" and the rear -0.5", the Tein S-Tech drops the front -0.9" and rear -0.7". Factory alignment can be obtained without any additional parts.

Swift Spec-R drops the front -1.2" and -1.0" rear and it looks like H&R will get you -1.5" front and -1.0 rear. Do I need camber kits or toe bolts for either of these?

What I would like to do is get the best-looking drop that sets the car even front and rear and add 15 mm H&R wheel spacers to the car to get a squared-off look. I have H&R on my 350Z with upper control arms, wheels with a different offset and different size tires than stock and I really like the look of that car BUT I get a knocking noise on the right front.

I want a recommendation that works GREAT and looks GREAT. I don't want to have any problems and I'd like to make minimal modifications to get factory alignment.

Lastly, if I go with a 265/35-19 (front) and 305/30-19 (rear), or equivalent setup when it is time to replace my tires so please factor that into the recommendation.

Thanks all!

IMO anything greater then 1" of a drop you will need camber kits in oder to pull them back to spec. But if you are asking the best-looking drop then the answer is simple - go lower or go home.:tiphat:

BTW - your screen name makes us look like cousins.:hello:

@forza370z, lol....I got that plate years ago after I got a lot of negative feedback from haters for my last plate ENVMYZ. Ahhhh memories.... :-)

:iagree:. The factory toe and camber bolts give you very minimal adjustments, so aftermarket camber arms and toe bolts are a good idea.

That knocking noise you hear on your 350z is probably the endlinks on your swaybars. Whenever you lower your car, it puts more stress on them since they are non adjustable. I went through the same thing with my 350z, until I bought the SPL adjustable endlinks.

So Eibach or Tein is the best way to go based on my requirements?

Well, since you mentioned that you were changing tire size, with smaller side walls than you are going to have even more wheel gap. If you want to go with a mild drop with the Tein or Eibach springs, I would stay with stock tire size.

Here is a pic of my Z on Tein springs, stock tire size. As you can see, its a mild drop.

I guess it makes sense to stick with the OEM tires sizes since they actually put good sizes on this model. My 2006 350Z 6MT came with 225/45-18x8" (front) and 245/45-18X8.5" (rear) tires/rims/width. I upgraded that to forged (lighter) Rays CE28Ns 255/40-18x9.5" (front) and 275/40-18x10.5" (rear). This package was actually lighter overall because of the lightness of the rims and the Michelin tires AND this made the car work MUCH better on corner entry and exit. MORE grip but not so little pressure per square inch that it didn't grip either.

Have you tried other tires, Michelin PS2, Hankook, etc in the NISMO sizes?

@MJB, it looks like the drop you have in that pic is pretty good for the 'real' world, would you agree? Did you go with any spacers? Also, do you have any close up pics of those RB rotors? Did you notice a big improvement with the better slotted rotors?

Yes, for everyday driving, or areas that have rough roads, the Tein springs are pretty nice. And I do have 15mm all the way around. Type in "Tein" in the search option and you'll see several set ups with those springs. I wanted to go lower so I eventually went with coilovers.

I don't track the car (yet), haven't notice any difference with stopping performance with the RB rotors. My car definitely feels lighter with the combination of the weight reduction I've been doing to it (front and rear RB rotors shed 24lbs) I'm moving on with a Wilwood BBK though.

@MJB, thanks for posting those up. They look pretty good. Any complaints or problems with the car? I've had three Z's before so I'm not sure why I'm on the fence about this one....

No different than any other thing us guys do...simply the latest greatest model. It doesn't matter weather you are talkin women or cars!:nutswinger:

Have you seen this?

Any more pics of the wheel gap with tein springs?

Well I bought the 2013 Nismo. I wasn't sure at first if this car was really better but it REALLY is. The Nismo suspension is quite good. That being said I don't want to undo what the engineers at Nissan accomplished. From what I can tell Eibach is the ONLY company that makes springs specifically tested on the Nismo edition of the Z. I want the best option for Nismo suspension that doesn't require me to change parts on the car to get the alignment correct. I kinda think the H&R sport coil overs would be a good way to go and only lower the car to the point it stays within alignment specs or get the Eibachs. Either way, I'll get the 15 mm wheel spacers.

Any thoughts on this? Does anyone know of lowering springs that meet these requirements?
