This is not a big update, but it contains some fixes and some new files.
Thanks to jcgrj for creating new sounds from the 2025 Red Bull RB21, which has been added to the mod.
Thanks also to Gitanes for his recently updated performance files. The average and track specific performaces have been updated up to and including the Brazilian GP.
And thanks to Excalibur for updating his Williams livery and rims with the Austin GP special livery.

Max Verstappen has been running a transparent wing on his helmet, so I have updated the helmet shape by Jvinu to reflect that in this mod.
There's also some fixes as well.
The Mercedes internal steering wheel has been fixed, some of the readouts were incorrectly positioned.
There was an error in the physics loading, that has now been rectified.
Thank you for downloading, enjoying and giving such good feedback on the new 1993 mod released earlier this year. My friend, KerleyF1 (grandprixmods.blogspot.com) and I have enjoyed working on this mod together.
Much of the credits for this mod goes to the Öggo, who worked on every car (except one) and given us the tools to modify this game more and more, and has worked on the whole helmet set, both shapes and textures (except one - my contribution is so small compared to this masterpiece).
Now with Öggo's recent release of his Bieffe helmet shapes pack, we now have an updated helmet for the one driver who used a Bieffe helmet in 1993, Gerhard Berger. It's really fantastic to witness the attention to detail and the skill to recreate it, and the true to life variety of helmet shapes just adds to the immersion of the mod in this game.
But this small update is not just one helmet, but thanks to rracunis for getting in touch and pointing out some issues with the internal cockpit. I do want to thank him for his contribution to the improved warning lights on the dash. I have now fixed the carbon in the cockpits, they are now much less shiny and also do not flicker.
So just a small update, but that's not to mention the number of hours that has gone into making them. I'm really grateful to work with so many different people in the community.
Installation and Download
Prerequisites
This is just an update to the existing mod, so you will need the original v2.0 mod installed, if you have not done so already.
Welcome to September's version of ICYMI, where it's basically news from what has been released for GP4 by authors across our great community. It's always good to see old and new authors modding different areas of the game.
It's here and ready - the 2025 CSM mod has just dropped.
As with my previous 2023/24 season mods, this mod is the base mod with everything working smoothly. So it is a kind of work in progress release, designed with future add-ons in mind.
The mods that I have released this year have been redesigned to make use of Öggos' InjectDLL and bringing new features to current season mods. Whilst the structure has many similarities to the previous seasons, it has significant changes means this is a completely new mod.
Much of the content in this mod has been released here: https://fongugp4.blogspot.com/p/gp4-2025-download-sources.html
All the cars have been brought to us by the RSCT team of Excalibur and Isaint. I have modified Isaint's cars a little, mostly bug fixes to stop the flickering textures and I have repositioned some of the rear wheel hubs to be more realistic.
I have also taken all these cars and created them for internal cockpit use. This is a new feature, and with the dashes on the wheel instead of the cockpit shape, it makes for a much easier conversion. Because these cockpits use the main texture, track specific liveries work seamlessly without any additional editing.
Also new, to go with the individual cockpits, are steering wheels for each team. They are based on the 2024 versions and both internal and external versions of these wheels are in the game. As it remains a limitation to run one steering wheel for all teams, you simply need to select a driver from the CSM menu to use that team's steering wheel.
Thanks again to Excalibur for his excellent 3D rims, however I have amended the size of them and created lods, as in previous seasons with Carl_gpgames.
Thanks once more to Gitanes for his work on performance files, including torque files, physics and magic data files for each track. The magic data, as in previous mods, is a little experimental, it does depend on how you install your tracks and the TSM profile name you use. I have added an option to turn the torque tweak off, this occassionaly makes cars sit in their pitbox for a good while before the mechanics start work - it is not a foolproof fix though.
Thanks to Mailson_Teles for his lovely loading screens and to jcgrj for the 2024 engine sounds.
I will talk about the new helmets in their own dedicated post, but I'm indebted to Theofilos for creating and sharing his Real Helmets Project. So far only the Arai and Bell helmet variations have been done, a very nice upgrade from before. Thanks to Excalibur for help in the conversion. Instead of waiting for the set to be complete, I have quickly painted some Schuberth and Stilo helmets on Jvinu's shape for the time being. These temporary helmets are not as accurate as the main set.
To get this mod released, I had to rush to put some generic items in, like high resolution team arts, plain pitcrews and engineers, not in any way accurate. There remains a generic internal visor. To get this mod released, I thought it was better to have something generic, and these can be patched later as people create them.
As always, thanks to a good number of community members who made this mod possible - some of them long gone from modding sadly, but their work is still being used to this day.

Installation Notes
Zaz Tools & GpxPatch
As with all my mods, you will need Zaz Tools and GpxPatch installed. You will also need to install CSM Process (CSM Add-on) for this mod to work too.
It's been a little while since I have posted on my blog. Inactivity on the blog does not mean that I am not busy working on projects, but mods takes time and dedication and sometimes real life has to take precedence.
You may have noticed, this site has been going through a bit of a rebrand, hopefully to make things easier to see and find. This is not least because there's close to 100GB of downloads now available on this blog.
However, that has not stopped the community from being busy and sharing their works.
There's been a flurry of activity on the 2025 cars, and Excalibur and Isaint have been doing a great job in bringing the entire grid to Grand Prix 4.
This is one is from the archives, thanks Ross Hunter for sharing it with me back in the day, and Quickslick for requesting this (or one very similar to this).
Here is the 1999 Arrows A20 as driven by Tora Takagi and Pedro de la Rosa.
This car is by Hega, with help on the car model by me, logos and reference photos provided by Quickslick, and some objects from Soulbringer's A19 model.
This car comes with 6 difference shape variants as well as a full season's worth of textures.
This is the car that appears in the GPedia videos with Mark Hemsworth
So what about the positives. It scored a point, back in the day when points were only awarded to the six. Admittedly, it was at the first race.
It was based on the beautiful A19, designed originally by John Barnard and Mike Coughlan, but the former star designed had since left and Coughlan and Eghbal Hamidy were tasked to develop the car with minimal funding.
It had in-house built engines, kind of. Tom Walkinshaw had injected funds into Brian Hart's engine company, but an ownership dispute ensued and Hart departed from the project.
Though both drivers were 'pay-drivers', de la Rosa would go on to prove to be a talented racer, and he is also the one responsible for bringing Repsol as a sponsor to the team. This resulted in the first orange Arrows of that short era, the front half of the car decked in Repsol colours.
As mentioned earlier, with investments from a Nigerian prince, the building blocks for a good little team was brought together. But sadly, with the funds not arriving, the departures of Hart and Barnard, meant the team were underfunded and underpowered.
Still, despite being such a slow car, it did beat BAR in the Constructors' Championship.
Around this time, 2 seater cars were kind of a thing, with Arrows building a 2-seateer and also the Arrows AX3 (3-seater car) was based on this A20.
On my side, I really enjoyed working on this car, I think it's quite a nice shape, and the sidepods are quite unique and a different challenge to making other cars.
Hega writes: Here's our tribute to Eddie Jordan. This was the most successful car in the team's fifteen-year history, scoring two wins, a pole position, and third place in the Constructors' Championship.
Thanks to fongu for the 3D model, and quickslick for logos, testing, and feedback.
10 different shapes + textures for full 1999 season included.
Earlier this year, the world is a poorer place after the sad passing of former team owner and principal, Eddie Jordan.
This is actually the second Jordan car I've been involved in releasing this year, but the 1999 car was where the team almost became legit championship contenders, they never looked so strong (albeit with no Michael and McLaren trying hard not to win). The trajectory was so promising that even Ron Dennis acknowledged it after their Monza victory. From there, the pole position at the Nurburgring was probably the epitome of Jordan GP. This car, to me, represents the hopes of my young Jordan fandom... just a shame it was downhill from the moment that Frentzen forgot a procedure at the pitstop and ground to a halt.
Most of the credit for this car goes to Hega, I played a little part with some shaping help, tweaking and refining what he had done. But I'm priveleged and grateful to be involved in helping make this new car for GP4.

The 1993 season has been faithfully recreated by so many talented modders from the community. Also,
It's been a delight to work with the nicest guy in the GP4 community, my friend, KerleyF1 (grandprixmods.blogspot.com).
For a long, long time, we had talked about updating the 1993 Mod for Grand Prix 4, and it's finally here!
KerleyF1 has done great work on the structure of the mod and the graphics and painstakingly installing all the track specific variants of the cars and helmets. In game graphics like the one below look fantastic.
This is built on the work on previous mods by TomMK (from GP4 Central) and Mschumi24.
And a massive thanks to Öggo who has been involved in every car in this mod, except one late season Tyrrell 021 which was done by me. Not only that, he's created all the helmet shapes and every driver has a personalised helmet texture do a level of specificity that is mind blowing. This mod also features a lot of his tweaks that have brought this mod to the next level.
I have learned a lot in making the 1994 mod, and it was good to carry some things over to this mod.
So what's new?
The top four teams, namely the Williams, McLaren, Benetton and Ferrari, have all had their cars resized to be more consistent with one another. For the Williams, I have also extended the front wing horizontally to be more accurate. GP4Central's mod also had low downforce rear wings, which have been incorporated into this mod, along with new lower lods for them.
New tweaks include removing the refueller from the animation, and starting the race with full fuel loads.
The 1993 steering wheel brought to us by Carl_gpgames is now included. With Öggo's tweak, this is now properly rendered in 3D and enables the advanced carshader. The external wheel was added by KerleyF1, and the arms are from Carl_gpgames, whilst the glove is an adaption from working in ChatGPT.
Carried over from the 1994 mod are the pit props and the marshall. I have also brought over the new high resolution tyre treads to go with the updated 3D rims and sidewalls by Alesi_fan and Öggo. There's also lots of customisable options in the CSM menu too.
Updated sounds by jcgrj are also carried over from the 1994 mod with some sounds by Mitsuro_Sano.
Also new to this mod are individual internal cockpits. This version is a bit more refined than the 1994 mod, and as the cars created for this were done with a generic dashboard, it means I can get a working dashboard on all teams, even though the positioning is different for each car.
I have also created new visors, these ones are more inspired by the ones in the 2011 mod.
Thanks again to Gap177 for his amazing work on the existing 1993 trackpack by Plodekk and cleberpister. Here's some more screenshots from the mod with some of the new HD tracks.
