Hi Nils,

I often see those wheels on Yahoo auctions Japan, nice, just a pity they are 13 inch diameter.

The gold colour (right) is fab, here is my "still in their boxes" Maglloy from Kobe Seiko with the same colour.

Yeah they're not very rare, tbh. I think Kobe Wheels in general are still a bit "under the Radar" when it comes to all the "JDM wheels" Hype.

So, I collected and got gifted a lot of cool stuff again over the recent weeks, and I have more updates coming in the next days ...

First, I finally got a set of good reproduction Carb insulators for the Mikuni 44 PHH's thanks to my man Glenn who helped me with those!


He was also kind enough to put a few nice freebies, like the 2026 JCCS calendar and a BRE fan into the box. Thanks mate!


I also got an original admission ticket from the 1969 Tokyo Motor show, where the S30 was shown first. This will go nicely into a frame next to the S30.world museum opening ticket:


From my man @RIP260Z , I got a very nice Kobe Sieko sticker reproduction, based on an original Sticker design. Thanks a lot, buddy - I love it!


I recently got laid off and my former employees were kind enough to give me a few thoughtful gifts for goodbye, including a Rally car die-cast, a Datsun flag and this beautiful card which one of my former team-members drew.

From my man Stefan, I got some cool NOS bits in exchange for some other items: a few relays, gaskets, steering coupler and drum brake parts:


This also included a set of Mystery relays which have a Su-I-Su (= Suisse = Switzerland) Stamp on it. We're both very keen to figure out what it is for. Most probably not S30 related but cool nonetheless!


Now to the stuff from Japan: I Sourced some cool vintage stickers, magnets and a Checkman horn button:

And a bit of a special Clay model, which I've been tracking and hunting since 2019. I will post about this tomorrow in a separate story.

And the probably rarest item: an original, NOS Group 4 racing overfender:


The former owner in Japan was a trustworthy source and the price was more than fair, so I had to get it.

@HS30-H confirmed that the Fabric and Part-number writing look correct for a factory part, so it seems to be a legit item.
I had to put it on my car just for fun's sake:

You might have realized that I've put it the wrong way around and on the wrong side of the car, as it first didn't make a lot of sense to me the other way around, but the FIA Homologation clearly showed me that I was wrong, and that cutout was for the G-nose front bumper.

The quality of this item is clearly a factory item. It's quite heavy, thick and stiff and the surface very smooth. Lucky me :-)
       

Here you can see how it's installed correctly on a car with the full bodykit. Picture taken from our visit to the NISMO HQ last year.

Stay tuned for more updates on parts and the car itself in the coming days!

Recently, I got a very nice Clay model of the HS30-H Fairlady Z-G blunt nose.

But this story started 7 years ago, in May 2019, when an Australian JDM-parts-dealer shared this on his facebook page. I was immediately hooked. Could it be an actual clay model from the design-phase of the G-Nose?

I started to go through my archive, and discovered that Nissan Indeed used 1:1 scale clay-models for styling and "rapid prototyping" by the standards of the 60ies.

In 1965, they switched to 1:4-scale clay models: 

They were used for flow testing in Wind-tunnels, water-channels and also for designing the exterieur.
   

I contacted the seller, but he told me it was already sold. Little did I know back then that the item was not actually sold. Neither by him, nor by the original seller. Probably it didn't get any bids, so it remained with the seller.
A few years later, I found a magazine article about a Japanese guy who owns some very special S30Z cars. and i noticed that exact same clay model in one of his shelves. the details made clear that it was the same car.

Fast-forward to 2025, where I met the Actual owner and his car at the S30.World Japan excoursin Meeting. And fast-forward some more months and now I'm the proud owner of that car. 

The car is made out of modelling clay, with an underlaying wood structure.

Some details like the windows are painted on and the overfenders (partially missing) seem to be made out of some styrofoam or something similar.
The details are quite accurate, if you ask me. So somebody must have spent a lot of time to get it right.

I was trying to find some marks or any hints that this car was originally used by Nissan, but there are no marks at all.

Some body gaps are made by using something like a foam-tape, which, unfortunately has lost its stickiness.

The length (without the G-nose) is about 80cm. Considering that the original car is about 4.14m sans g-nose. This is about an 1:5 scale model. 
So considering that there are no marks (I would somehow expect that from Nissan), and that styling prototypes probably never left the factory, Plus the fact that a model with such a construction doesn't make a lot for usage in a wind tunnel, if you ask me - make me believe that this is something else. Either it was a hobby project of somebody, or something else. Either way it's a cool piece of history and I love it.

My understanding, from looking at the CSP311 design, that the modelling clay was initially supplied in the early 1960's by Chavant, made with bees wax and is easily worked at 40 degrees c. And its red in colour, you can see red on worn bits of the clay model, the same material....?

Hmm very interesting. It has definitely a red colour and a very specific smell. Could smell like bee's wax. I will sniff on it again tomorrow. Never thought about bee's wax.
They must have used tons of this clay to make the 1:1 scale models. Talk about busy bee's

About year ago, I managed to find a complete set of somewhat rare Nissan height-adjustable competition suspension.

Back then, I discovered that one of the rear springs was shorter than the other one, which was a bit strange.

The catalogue however clearly mentions 205,5mm's free length, for both sides, on the rear springs 55020-E4621:

The difference might have occurred due to wear under racing use, or long-term storage in compressed state or whatever, but yeah it was a bit strange. My thinking was that I probably would not sense a big difference once they are installed in a compressed state, so it didn't really bother me. But then, I came across these for sale: A NOS set of 55020-E4621 springs. It's probably not often you will see a set of unused springs for a competition adjustable suspension, still new in its original box, with all the stickers still on it.

So I HAD to get them:

Once unpacked, you can clearly see that the two old ones on the left side had been repainted at some point with a flat black (vs glossy black on the new ones) and that indeed one spring was shorter:

That means, that my adjustable competition suspensions is pretty much complete now and ready to be overhauled. Excellent. And a bit unexpected, but I'm more than happy.
But that's not it. While going through the boxes to put together the suspension for the Photos, I opened a box of spare parts that came with some of the suspension parts. I remember it had some unknown springs and strut inserts inside. Back then I removed one of them from the packing and could only read "KYB" (= Kayaba Brand) and a part number. I quickly googled the numbers back then to find out what it was, but couldn't find any information, so I just put them back in the box as "random aftermarket" parts that came with some other stuff.

Well today I was about to through them in the bin, since I had no use for them, but inspected them a bit closer before scrapping them. And...? I just found out it's actually a set of NISMO dampers in still quite good shape:

56110-RRE72 and 56210-RRE72. The springs have no markings on them, so not sure if these are NISMO too, or any other aftermarket or OEM springs.

I tried to find the part numbers in my various old NISMO / Nissan Motorsports / Competition catalogues, but wasn't able to find them. A quick google search pointed my towards my own suspension post on this very website, where I showed a similar set with the same part numbers that was Sold on Yahoo auctions years ago specifically for the S30. I'mm still trying to find out more. The NISMO logo tells me that it must have been in the 80ies / early 90ies that this set was sold. But I'd like to find out what specification it has, and for what specific type of racing it was designed.  If you have any input on this specific dampers and the springs that came with it. Please let me know.

So at the End of the day, I have a full adjustable suspension with some extra spare parts AND a set of NISMO dampers. The day could be worse :-)

Hi Nils,

Nice stuff!

I have an issue of the NISMO 1997 Japan catalogue that lists the 'RRE72' Kayaba blue NISMO cartridge inserts and their corresponding springs: *54000-E7211 SPRING COIL KIT FR & RR.

The listings states that they are for use with standard strut platforms (ie, non-adjustable ride height), they lower the car by 60mm and the spring rates are FR: 4.0kg f/mm and RR: 4.8kg f/mm.

There's a note that says the 54000-E7211 spring set is essentially the same as the older Sports Option 54010-E7211 (FR) and 55020-E7211 (RR) springs. So they just have new part numbers.

Actually it might be easier for me to scan the relevant page and put it up here, because there is additional data for the springs and dampers which might be of useful reference for you. Stand by...

@HS30-H : is it from this one? I might want to find a copy anyway. I still have those other mystery struts which I need to identify, and it seems there is a bit of a gap in my documentation.

Similar design, but my version has a metallic silver cover.

Here's the page in question. Doesn't scan so nicely because I don't want to break the spine, sorry:

Thanks a lot, Alan. I Appreciate ❤️
