Many thanks to Martin18 for providing information on the length of the lower arms, he was able to find and the current wheel sizes that he noticed in the photo. And information on aerodynamics, but with a road version and bit different version of the body kit. I also managed to find the 2022 GT4 Tire Use Specifications. Martin also tweaked the engine a bit.

I also found an interesting article on body aerodynamics, it turns out that almost all road car bodies create a lifting force (except for those that do not have a rear slope of the car as in station wagons or vans ). Adding a little spoiler helps with that, but not completely. https://www.drive2.ru/l/4655805/ The article is in Russian so you may need a translation app or something. Since I have a spoiler installed (which is on the body and not from the GT4 version) I made a small lift for the body. But the spoiler, splitter and underеtray are quite sufficient to create enough downforce.

Mod was updated:
Changed wheels size.
Changed suspension.
Changed frame.
Changed aero.
Changed engine rpm values and redline.
Fixed brake calipers.
Changed some mappings.

Updated default setups.

Updated default setups.
Updated aero.

Mod was updated:

Added some mesh (plane in side vent, welding in visible roll cage from pov, front bumber holes cover, etc).
Updated default setups to more racier and added 2 new ones. (Sport setups removed)
Some mappings fixed.

Modern racing digital dashboards have changed a lot, and they contain a lot of different information.

It would be great if the texture on the digital dashboard had data on the best\last\ lap time, sector time, time to the next driver/chaser/leader, position in the race, rpm, selected tires, tire pressure and temperature, as well as indicators of pressure on the throttle pedal and brake pedal (maybe in one bar), and enabled ABS and traction control in the setting.

In addition to the dashboard these indicators will also help to display them on the car itself, as it happens everywhere in motorsport, for example in some GT series position indicators are displayed on the windshield, or in drift competitions pedal indicators are also displayed on the windshield.

Mod is submitted for review, please support it🙏
Now the mod is required for testing, whoever wants to please test it and give feedback

https://www.lfs.net/forum/thread/107832-POSCHER-CAYNAM-718-GT4

Update posted:
Fixed internal mirror.
Added pit limiter light.
Fixed aero to balance with porsche GT4.

The final touches took a little longer than planned, so I made a video.

Researchers from the University of Illinois at Urbana-Champaign recently published a study in which they proved that OpenAI's GPT-4 artificial intelligence model is capable of independently exploiting vulnerabilities in real systems after it receives a detailed description of them.

The study selected 15 vulnerabilities described as critical. The results showed that the GPT-4 language model was able to exploit 87% of these vulnerabilities, while the other models were unable to do so.

Daniel Kang, one of the authors of the paper, argues that the use of LLM can make exploiting vulnerabilities much easier for attackers. According to him, systems based on artificial intelligence will be much more effective than the tools available today for novice hackers.

interior preview

I made small update:
Added front\rear EU numberplates in different configurations.
Lod2 holes fixed.
Lod2 Skin Mapping applied.
Lod3 Skin Mapping applied.
Some geometry fixing.
Some mapping fixed.
Skin mapping a bit changed.

Quote from OpenClutch :

There already is a 180sx or 240sx that allows derivatives (which is fully...

I don't need this for the N.S80 mod, because I will try to keep the handling from the current version, and for this reason I can't really change the suspension geometry and physics.

Since the interior model is almost identical to the GT4 Version, the model is almost complete. There are still small final touches that I will probably do without video.

Quote from Latvian Video :

if it doesn't change the physics, sure

The handling will change one way or another after the dimensions are changed

I will go over my mods and plans for new ones. Since I modelling all my own models the readiness of the planned mods is considered as 50% model and 50% everything that is done in LFS Editor (physics, texturing, animation, etc.).

Nissan Sileighty (N.S80) Status: - Approved. Rating - 4,42 (208)
The mod is mainly for drifting. It has 4 different configurations with different bodykits. And it has been completed for a long time, one of the most popular mods in terms of downloads and number of ratings, but maybe it was because I made it one of the first, but on the other hand the rating is not the best mainly because of the objective shortcomings of physics and because of unrealistically extended body, but now it's been quite some time and the mod is loved by many people for its peculiar flavour of handling, and I can't decide what to do about it. If I change the body geometry to the stock wide, the handling is likely to change.

And I'm not sure what to do about it, so I've attached a poll. Is it worth changing the body width to fit the stock or is it better to keep it as it is?

Nissan 400Z (N.400S) Status: - Staff Picks, approved. Rating - 4.7 (109).
Finished the Z not too long ago and it turned out to be a very good handling and detailed mod. I've already had some competitions with it and received quite a lot of positive feedback. Also the developers considered this mod worthy to be included in the category "Staff Picks" where quite a few mods get, a big thank you to them from me

Nissan 400Z GT4 (N.400S GT4) Status: - Staff Picks, Approved. Rating - 4.7 (77).
The GT4 version of the Z was also recently completed. It received a lot of attention, including during the championship GT4 series where my mod was presented as single one in the class. There was a lot of feedback from pilots and scawen, which helped to make the final touches that optimised the mod. This mod is also presented in the "Staff Picks" category, which makes me one of two people who have 2 mods in this prestigious category at once For what again thanks to the developers.

Nissan 400Z Drift spec. (N.400S STREET DRIFT) Status: - Approved. Rating - 4,86 (38).
The drift zeta is still in the process of final tweaking, although it's my highest rated mod so far, probably because it has 5 different bodykits configurations, including Gocha new bodykit, Chris Forsberg's bodykit from last season and some others. I already know that the mod is loved by many drifters for its handling and for visual, and this fact I can only be happy.

Porsche 718 Cayman (POSCHER CAYNAM 718) Status: - Published. Rating - 4.74 (32)
The Porsche Cayman was also published the other day. A sports coupé with a centre-engined layout. The main updates have already been done and now it only remains to be finalised. But already now this mod has received probably the most feedback. I think maybe after a while this mod will be approved too.

- And then there are the planned mods. -

Porsche 718 Cayman GT4 RS CS. Ready to submiting: 80%
This mod will be a good addition to the GT4 series. An important clarification that this is the version for the competition racing series GT4. And not client GT4. These are different versions of the cars. This mod is my main priority for development right now. Although away from my home computer I have time to modelling other mods at work when i have free time.

Ford Mustang 2024 Dark Horse. Ready to submiting: 50%
The model is now complete. All that's left is to get it all into the editor and start making it.

Ford Mustang 2024 GT4. Ready to submiting: 50%
Also only the model is ready.

Porche 718 Cayman GTS. Ready to submiting: 45%.
A more powerful version of the Cayman with an atmospheric 6 cylinder flat engine. Since the basic model will be taken from the default cayman and will remain to do all sorts of little things on modelling, we can say that the mod is ready for about 45% But while a high priority on the development of this mod is not planned, because there are more important mods, such as the following in the list.

Ford Mustang 2024 GT3. Ready to submiting: 45%.
A racing version of the Mustang in the higher ranked GT3 racing series. Some of the parts I'll be able to take from the gt4 vers. This will be my first mod in this class, so I will need to gather a lot of feedback from the drivers of this series before publishing, I plan to make it before the summer. Hopefully it'll work.

Ford Mustang 2024 Drift spec. Ready to submiting: 20%
Drift Mustang with bodykit of RTR team which performs in Formula Drift series. Probably later will be made other bodykits.

Further already more distant plans, and to be more precise just some thoughts, for example to make in the future drift cayman . Why? Denofa did it, maybe I will do something like his version.

I have thoughts to make a client version Porsche 718 Cayman GT4 RS, essentially the same GT4 racing version only with the usual road interior. And a slightly modified body design.

Also there are plans for KTM X-BOW GTX. Somereason this car caught my eye, even though I'm not really into supercars. If everything goes smoothly with the GT3 Mustang, I will probably do it too.

Also planned further expansion of GT4 class, because in terms of mods now actively engaged in it only me. For example, I'd like to make an Aston GT4. And maybe even a BMW GT4. Despite the fact that I didn't like it initially and I didn't even include it in the poll. I've revised my views and I'm considering it too. As always I plan to do all modelling myself (except if someone wants to expand the GT4 series but has no modelling option and he already has a mod in LFS to fit the gt4 racing clas, then I could make a version of another existing mod in LFS (for example with an Audi R8 or BMW M4 model). I also wanted to make a Toyota GR86, but then something didn’t work out and it seems that it has already appeared in LFS. I was also thinking of doing a stock Nissan 180sx and a stock Nissan Sileighty. But such mods are already out there and I'm not sure if it's worth the time. Plans for further mods are constantly changing and therefore I may do something else in addition to the above or I won't be making some of the mods I had planned for the long haul.

Ok, I found this, I guess it can be considered a plus outside the context of the minuses.

While this paper focuses on harm, we recognise that cars and automobility offer important benefits to some people. They connect isolated towns and rural areas. Cars and automobility can provide transportation for people who have physical disabilities (Power, 2016). Car interiors can be sites for conversation, enjoyment of music, privacy, safety, or a respite from the outside world (Dobbs, 2005; Laurier et al., 2008). Cars can influence people's sense of self and fulfil symbolic and affective functions (Steg, 2005). These benefits are important for the people they affect, and interventions to reduce car harm need to take them into consideration.

This paper does not adhere to a utilitarian cost-benefit analysis framework wherein “costs”, e.g. harms caused by automobility, are compared with the “benefits” of automobility, e.g. those listed in the previous paragraph. It instead focuses directly on harms, as these have been deprioritised in decades of research and policy that suggest modifications to automobility (e.g. electric or autonomous cars) rather than the more politically controversial option to challenge the system of automobility (Culver, 2018; Sheller, 2018).

Okay it's not propaganda. Although the overwhelming amount of text there is about the harm of cars, although it is clear from the stated topic.
