Apologies for the delay in releasing this, but this is the 2025 helmet set.
With Jvinu's shapes becoming increasingly out-dated, I was glad to see that new helmet shapes were being developed. ASCPRH had now progressed to version 2, and whilst I had permission and agreement to work with Marco_17, I was unable to contact Daimon for his permission of his helmet shapes. So I was glad to see that Theofilos, some of whose helmets I had converted to GP4 before, had started working on new helmet shapes.
The project is called 'The Real Helmet Project' (RHP):
As previously explained, the converted helmets of the Arai GP7 and the Bell HP77 are from the pre-VRC release of the Real Helmets Project (RHP) by Theofilos.
Nick9320 and I reached out and struck up a working relationship at the time and whilst this project has taken time, I am glad for the helmet upgrade and I think it has been worth the wait. For the time being, we wait for the Schuberth and the Stilo helmets to be made, I continue to work on Jvinu's helmets for the time being.
There are two visor strip versions on the Bell helmet, as well as two wing options. The colour of the driver internal fabric is also specific to each driver now. My thanks goes to Excalibur for helping with the conversion. The hans device remains Jvinu's version, simply because it fits GP4 driver bodies better.
Theofilos is a very talented 3D and 2D artist, and he has painted both Mercedes helmets and the Ferrari helmets, they look stunning.
Credits
All helmets have been designed from scratch with a focus on accuracy and high-resolution detail.
Arai & Bell helmet – is from Theofilos’ Real Helmet Project (pre-VRC versions) and converted by Excalibur
Ferrari & Mercedes helmets – are painted by Theofilos
Schuberth & Stilo – templates by Jvinu (ACSPRH v1)
Every helmet has been recreated from scratch in 4K resolution, bringing the current F1 grid into GP4 with improved clarity, sharper detail, and more accurate representation of real-world designs.

This release couldn’t happen without the brilliant work by others in the community, with helmet shapes and templates by Jvinu (ACSPRH v1) and Theofilos (RHP).
All helmets have been designed from the ground up, with a focus on accuracy and high-resolution detail.

Driver-Specific Features
This pack reflects the current F1 grid as closely as possible, with each helmet matched to its correct shape and visual identity.
Helmets are not interchangeable — each design is built specifically for its intended model.
Verstappen
Number 3 added to the transparent wing.
Charles Leclerc
HP logo added to the transparent wing (Ferrari helmet).
Lewis Hamilton
HP logo added to the transparent wing (Ferrari helmet).
Valtteri Bottas
Finnish flag added to tear-off strip handles.
Final Notes
I hope you enjoy this new helmet set and its improvements. Each year, I try to add a new level of realism and accuracy. This season it is the 4K textures and some new specific shapes for drivers.
Today I’m excited to share the latest additions to the 2026 grid: the McLaren MCL40 and the Haas VF-26.
As mentioned previously, this year’s cars have been split between myself, Excalibur, and Isaint—so this release marks my final contribution to the 2026 lineup. Huge thanks to Excalibur for the outstanding work on the new wheels and rims; they really elevate the overall look of the cars. You may also spot an early preview of the 2026 helmets, with a full release to follow once they’re complete.
McLaren MCL40
The McLaren team continue to use the benchmark Mercedes power unit and having not had an ideal start to the season, nevertheless showed a competitive outing at the recent Japanese Grand Prix.
It was a refreshing change to work on something closer to the sharp end of the grid—my earlier allocations seemed firmly rooted at the back!
Haas VF-26
The Toyota backed Haas team have fared well in the midfield, with some reasonably strong showings so far. Nothing spectacular, just good solid progress with capable drivers behind the wheel.
After many years of quite bland and dull liveries, the Gazoo Racing effect has produced once of the better looking liveries on the grid.
As with my previous release, you will find the internal cockpit shape for each car, along with the collision mesh file.
In the background, work has begun in compiling a mod, and when all the cars, helmets and a good set of physics are shared, I will release a CSM and a non-CSM version of the mod. Until then, I hope you enjoy these new additions to the 2026 grid.
The 2026 F1 season is now under way, and so is work on bringing the 2026 grid to Grand Prix 4.
I’m thrilled to be able to partner up with the RSCT team and divide up the work between us. I'm grateful for Excalibur and Isaint, veterans of the GP4 modding scene and the dedication they have to keep preparing and sharing up to date cars with you each season. Indeed, my contribution this year is indebted to partnering and discussing and sharing resources together with them.
Even things like a shared light texture, wheel sizes and positions, and some geometry discussions have all helped to create a consistent, polished release.
And today, I’m excited to reveal not just one car, not two, but three cars from the 2026 grid! The regulations are so tight in some areas that some parts of the car can be reused for each car. However, each team has still explored unique aerodynamic philosophies, giving every car its own character.
Alpine A526
I have for you the Alpine A526. Having ditched their own engine programme, they are now Mercedes customers, and they did well to negotiate a deal with what appears to be the benchmark Power Unit on the 2026 grid so far. The styling and presentation of the team is very similar to 2025.
Aston Martin AMR26
There is also the Aston Martin AMR26. Working on the British marque is always a highlight, though nailing the perfect green in-game is a challenge! This year’s AMR26 is striking, clearly bearing the signature of Adrian Newey’s design philosophy. While the Honda power unit isn’t quite up to scratch yet, at least you can enjoy a reliable car in GP4. Why not crank your force feedback to 400% for a more realistic experience.
Cadillac MAC26
And then I've also worked on the Cadillac MAC26 - a nod to the founder of the project, Mario Andretti and his son, Michael. Sadly, it's another bad episode of a tumultous relationship between Michael and F1, but I am so glad to have the right number of teams on the grid to fit GP4! Its asymmetrical livery might not be to everyone’s taste, but it’s guaranteed to stand out on track.
Please note that the rims and helmets shown here are experimental for now. Excalibur is hard at work on a dedicated 2026 tyre and rim pack, which will bring everything together visually once the full set is ready.
Included in each pack are the car shapes and the textures as seen at the Australian GP. You’ll also find the internal cockpit view for each car, along with the collision mesh file.
Thank you all for your continued support of the GP4 modding community.
I hope you enjoy these new additions to the 2026 grid.
It’s time for a new compilation of the 2004 Track Pack.
Since the original release in 2023, a number of community improvements have emerged — particularly updated liveries and revised layouts based on the F1Virtual versions of several circuits. Rather than leaving those improvements scattered across separate downloads, I’ve consolidated them into a cleaner, updated v2.0 package.
What’s New in v2.0
Magny-Cours
Now includes Josekast’s updated livery set, based on the F1Virtual version of the circuit..
Spa-Francorchamps
Updated to the correct layout, incorporating work by MarioB, btone and others. This version better reflects the configuration used during the 2004 season by Josekast.
Hockenheim
Revised with Josekast’s livery updates, again based on the F1Virtual release, bringing improved sponsor placement and trackside detail.
Sakhir (Bahrain)
Now uses the newer version of the circuit by F1Virtual, replacing the previous version that updated the old layout.
Shanghai
Updated version by Naitch7, based on the F1Virtual release.
Additional Inclusion
I’ve also included the 2006 Suzuka by KTC. It is not selected by default within the trackpack, but it’s available as an option.
This version features the altered final chicane layout, which more closely reflects the later configuration of the circuit. It is slightly buggy in places, but I felt it was worth including for those who prefer the revised chicane geometry over the older version.
I hope you enjoy this little update to the 2004 season from the best currently available community updates.
V2.1 includes a fixed version of Indianapolis - by Ricardo Lampert and hi-res textures by Caelen.
Installation Notes
2004 Trackpack v2.1 (for TSM)
This release is set up to be used with TSM - just extract the files into your Grand Prix 4/Tracks directory.
