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).
