oh by the way...how tensile is this aluminum? no point in swapping the stock one if its just as flimsy. thanks!

They are made of .063" thick Aluminum, Lightweight and strong, MUCH stronger than the plastic crap.

Part #75895 is useless. Mine was dragging on the ground while driving as well. Bought new push pins,glued the crap out of it and still comes loose from airflow. Clearly for me, thats a poorly engineered part to cover up a mistake when they molded our Nismos under tray. I say mistake because why create an air pocket for a part thats designed for aerodynamics? All it does is allow air to flow into that molded space and finally rip part #75895 off. Why not make it straight? Whats up with the bubble? Can anyone elaborate why nissan didn't this? Correct me if I'm wrong for example.
Looking at a Gt-Rs under carriage you won't find plastic pieces to patch up its oil drain cover. I know its not a gtr but still, why us Nismo owners gotta be treated like the step child? Were family!
For me, I eventually gave up on putting that plastic piece back on again and again. I also have my under tray zip tied from the air damage. Lol
So Joe@zspeed. Great job on your project brother. Make 1 extra... cause I want 1 to.:hello:

Nismo shields are ready, Check website or Classifieds!

sweet..now to save some money. however..how come the nismo version is so expensive? nearly double the price of the normal Z. just because nissan gouges us ALOT more for the nismo, why are you guys charging us so much? its not THAT much more metal

just a legitimate question..:icon14:

I agree. I'm in sticker shock right now. Give me more time to absorb.

There is a ton of work in these pieces and nearly twice the material that is in any of our other shields let alone the 3 months I spent working on this.

Design time, Layout, Cad designer, Prototypes, Special tooling, This all adds up, I invested quite a bit into this limited piece run that I will probably not see a return on with the small numbers these are going to be.

These are actually priced a lot cheaper than they should be from a business stand point.

Everything with the word NISMO is going to cost more.

Given the R&D involved on the part of ZSpeed and the fact that there is a lot LESS opportunity to sell the NISMO versus the regular 370, I think the price is reasonable.

Plus it is a better and cheaper alternative to the OEM piece.

Limited Market = Higher Market Price

Supply and Demand Relationship

can we hear what R&D actually went into this part? did you drive with it on at least? how about any impacts? when plastic rips off the bottom of your car it dosnt do much damage. but if this part failed aluminum can get dangerous at high speeds.

im not saying its a bad product, just need to justify the price.

also how much more does it weigh than the factory plastic piece? meaning are the black plastic clips enough to hold up the addition weight?

There are over 20 bolts holding this on the car, It ties into many different areas, It is not held on with just 3 clips. Nothing dangerous about it, Not like it's 1/4" plate aluminum.

Some specs on the aluminum we use
Tensile strength 33,000 PSI
Shear strength 20,000 PSI
Thermal Conductivity 960 BTU-in/hr
Elongation at break 18%

There is about a 4lb difference between stock and the ZSpeed pieces.

We have a local person with a prototype piece, he added the Nismo bumper to his base model and found that the stock plastic pan was over $1,400.00 so we hooked him up with ours. It has been on for quite awhile now with no issues.

Another member on here with a factory Nismo we wanted to use for test fitting to make sure it fit the same has had it for the last few weeks and had it installed down at Z1 motorsports. I'm sure he will chime in if he reads this.

I have had our original 370Z piece on my car for months, we have had them on 350Z's/G35's/300zx's for years now tested on the track at very high speeds and have saved more than one oil pan and likely engine in the process from track debris.

If you ram a curb with it obviously you will probably damage it but it is for Aero, not a battering ram.
If it gets damaged, you should fix it before it comes off.

We've used what we have learned on other shields to make this the best we could, Could we have done it cheaper? Probably, but I don't cut corners or use cheap materials to save a few bucks.


Hopefully this will help answer some of your questions.

Without a doubt the part is well designed from where we sit. Not taking anything away from its development. Im far from being a person with short arms and long pockets.
Fuct does make a point about the R&D. Knowing that the Nismos front end does sit lower and most of us arent stock height, on impact will the part hold up? Our oem plastic piece is expensive but did withstand impact pretty good. Minus the rectangle piece. lol
I dont think weight matters to me much. the heavier the gauge the better.
Titanium would be nice.

This is the new 370Z V2 shield that has less mounting points than the Nismo. I am holding onto it between the mounting points in the weakest part of the shield.

I am not 150lbs either ;) Maybe I'll start doing my pull ups in the garage.....

I'm sold...

haha. nice write up. how limited are these in production?
