New Suspension add-on for the Z1 370Z Shop Car
 

We just got this kit in from Nissan Motorsports, its the add-on NISMO Brace Kit for NISMO 370Z. These pieces come stadard on the NISMO Edition cars, but are not present on the non-NISMO versions.

We will be doing the install later this week!

Here is a quick peak at the kit:

The Two Silver Braces go on the underside of the front suspension and the Black/Red Brace actually goes in the interior of the car just behind the driver.

awesome! can't wait for the pics! :yum:

Interesting...this is the first time I have heard of chassis-bracing exclusive to the NISMO 370Z. Never has this been mentioned in any discussion on the forum or officially from Nissan. These pieces come from the factory on in the US-market NISMO 370Z, or am I misunderstanding something?

Either way...very nice. Stiffening the chassis is the single best improvement you can make to any sports-car. :tup:

:iagree:

Are these bolt on pieces or do they require some custom fab (at least the one for the interior)?

Well in any case, eagerly waiting for the installation pics! :icon17:

they're some nice lookin pieces

They are straight bolt on pieces. Th Black Bar actualy mounts under th rear carpet section, so you wont actually see it when installd. The two silver bars attach under the front suspension. I believe this is why people have not caught on yet that they exist.

The part has been available in Japan for some time now, but has just recently been released in the US. We have the first 2 kits in the country here now.

Dustin hurry up with the installation and pricing! :p:p

+1 for great customer service btw! :tup:

Great Stuff :tup:

Will you write us a review, after you test them ?

Most definitly, I am in the process of doing a full write up on the install aswell. We are hoping to get some more track time in the next few months to play with the new additions, as well as some others in the works.

I have the rear brace installed already and it is very simple to do. I will go ahead and say this. By adding the NISMO Brace on the rear of the 370Z, you not only stiffen the chassis. But you also free up some space under the rear floor board to hide a stereo, etc.

Interested to see how that works. Hoping you do a write up of an OS Giken as that will be my next purchase and be from Z1 !:happydance:

Bump!

Dustin where you at?!? :p:p:p:p

He is working on some of it at this moment.

Sorry in the delay for getting back to you guys. I have spent alot of time taking pics and documenting the install of the NISMO Brace Kit on our shop 370Z aswell as running around the shop.

First off, I want to appologize for being somewhat misleading. Based on what was instructed to me, I was under the impression that the braces went only on the lower part of the front suspension and the upper rear (interior). From doing this installation, (given that the directions are ALL in Japanese) I have now learned that the braces actually go in other locations. The braces are mounted:

1) In the bumper of the car, joining the front frame rails. (In front of the Radiator)
2) On the lower portion of the rear suspension, connecting the suspension arms
3) In the interior, joining the rear frame rails.

Here are only a FEW of the pics I took while doing the installation. I will be doing a full write up over the course of the next few days and will post it as soon as I get it done!

I will go ahead and mention the following points:

- Everything was done with basic hand tools and would take a few hours to install. It took me considerably longer since I was documenting the steps as I went along.
- The Rear Upper Brace does not require any modifications to the interior whatsoever and is completely hidden once installed. (I also noted that it frees up alot of room under the carpet for hiding stereo components, etc)
- The Front Brace CAN be installed without removing the bumper and does not interfere with the Nissan Motorsports Oil Cooler, as long as both are installed following the directions.
- The Front Brace WILL NOT interfere with the Stillen Stage III Intake.
- Installing the Rear Lower Brace will require a Lift, or set of suitable Jack Stands and floor jack. (Exercise Caution when Jacking up these cars!)

Anyway...now for some pics

I will begin with the Front Chassis Brace that connects the front frame rails. The brace will replace two existing brackets that join the frame rails to the metal core support plate between the radiator and the bumper.

Once installed, the brace actually is tilted backwards towards the condensor/ radiator cores allowing for plenty of clearance for the Stillen Intake and Nissan Motorsports Oil Cooler.

Installed, the brace is hidden behind the bumper and other associated plastic panels.

To install the rear brace, the rear interior panels must be removed in order to facilitate the removal of the Foam Bar that sits below the floor. This piece will be replaced with the Brace itself and a new floor panel in this area.

Once installed, no one will know that the brace is even there. In addition, the brace does not take up any cargo room in the trunk and actually frees up room under the floor for hiding amps, brain boxes, etc.

The Lower Rear NISMO Brace attaches using the existing hardware found on the car. Our shop 370Z has a custom exhaust and even with the brace installed, we had no vibration/ rattle issues whatsoever.

The NISMO Brace kits are priced at $795.

We will be hopefully putting our Z on the track later this month to play with these new braces!

Looking GOOD!

isn't there a stablilzer bar of some sort that runs along the front on the nismos too? i remember seeing it on the white one i was looking at

Yes, there is a steering dampner that runs across the front as well. I freaks people out since it says YAMAHA on it.

Awesome! I can't wait! :happydance:

When do you think you'll have these available for order?

if only it were affordable.. lol

I like it!

Very cool! As I mentioned, chassis-reinforcement modifications are some of the most overlooked and under-rated modifications you can do to improve how the car drives overall. Can't wait to see more about this setup. :tup: :tup:

My question still remains, though...which NISMO models did these pieces come from the factory on? Are these on the Japanese-market 370Z NISMO which Nissan left out for the US-market?

I m not entirely sure, I will take a look at one tomorrow and see. Like I mentioned, unless you know what to look for. These braces can be overlooked and go unnoticed.

Dcrew1x...I will have them on the website by Friday for sale.

What is the metal box with all the wires going to it in this picture? My car does not have that but that is where I put my amp.

Is your car a Base model without the Bose system?

That is the Brain Box/Amp for the Bose system with Navigtion. Our shop car is a '09 Touring with the Sport Package. If you look to the right, you will also see the factory Bose subwoofer hidden in the spare tire. What is interesting is that there are ALOT of unused plugs on these cars. I would like to know what else the cars are prewired for.

I know that the JDM cars have reverse looking cameras, rear wipers on the back glass as well as a few other JDM only features.

what exactly does it do? never heard of such a thing except on bikes

Dustin, this might be a seemingly easy question, but I hope you can show us in your full write up how to remove that rear trim piece behind the seats. I've tried to remove it, and the ones on either side of the spare tire before and just can't seem to find 1 screw or something holding them in!

It's actually a body damper to tie the front frame rails together. Nothing to do with the steering actually....

Thanks Modshack, I referred to it as a steering dampner due to riding bikes for so long. I m use to having the steering dampner on the column of some of the Yamaha's and Suzuki's I use to ride.

No problem with the install pics on disassembling the interior. I will get them up on the forum tomorrow. There was a trick to removing the center piece. It is a combination of lifting up and pulling towards the front of the vehicle.

Sweet Can't wait! :bowrofl:

Much appreciated man!

Just went outside and checked my car. None of these braces are in my Nismo. :( should I be pissed?

Hmm...this is what I am wondering. Most NISMO edition 370Z have the Stabilizers that are being discussed in other threads. These might be additional braces from NISMO Japan. I would like for any other NISMO Z34 owners to chim in on this one and let me know, are these braces present on your car from the factory or not?

Nope. We don't get these on our nismo's. We get the body dampers, additional bracing of the front strut bar and the nismo sways, springs and struts. Plus pretty red stiching! Dustin, let us know when ya'll run the car on the track as I would love to know what the effects of these pieces are. By the way, I didn't see these listed on your site, do you have the other set for sale? I am headed to the track on the 30th. Maybe if you sold me a set i could test them out......?

Strut-tower bracing appears to be the same in all Z models.

PM Sent!

I believe that the NISMO strut brace is different. There are two additional that branch out from the Main bar across the engine to the little arms that go to the firewall. Non NISMO 370Z have 3 pieces total making up the strut brace, the NISMO's have 5.

That is correct. They stiffened up the bar by placing a short piece five or six inches further down the bar, kind of like a gusset. When I get home I'll post apic.

I stand corrected. :tup:

Just for the record. My understanding is the Nismo 370Z has, 4 puck type chassis dampers, two piston type dampers, anti-roll bars, and two addition braces on the strut tower bar. These are the only changes as far as chassis rigidity goes that I am aware of.

Never seen the puck type dampers. Where did read about or see those? Inquiring minds want to know!
