GP4: 2004 Track Pack v2.0

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.

GP4: Real Helmets Project – Arai GP7 & Bell HP77 Templates

 

I’m very grateful to Theofilos for starting the Real Helmets Project for Assetto Corsa last year. It’s an incredibly detailed and well-researched helmet project, and it immediately stood out for its accuracy and modelling quality.

With his permission, both myself and Nick9320 (who now primarily mods for rFactor 2) were able to convert the work to our respective games, helping bring a consistent, high-quality helmet standard across multiple sims.

So far, the project includes:

• The Arai GP7

• The Bell HP77

Both helmets come with various clear and solid wing variants. The Bell HP77 also includes the alternative wing specification used by the Ferrari drivers, again available in both clear and solid versions.

In addition, the Bell features multiple visor options:

• Standard short visor strip

• Extended visor strip variant

These small details make a big difference when recreating specific drivers and seasons accurately.

I’ll admit this release took a little longer than planned. Part of that was waiting to see whether Theofilos would be adding the Stilo and Schuberth helmets to the project. In the end, he shifted focus toward improving the driver body model in collaboration with the VRC modding team instead.

You can find the original Assetto Corsa release here:
https://www.overtake.gg/downloads/vrc-rhp-real-helmets-project.75985/

Today, I’m releasing the converted helmets for GP4 (kindly converted by Excalibur), along with the original templates provided by Theofilos.

The key benefit of this approach is compatibility. Helmets created using these templates will now work consistently across all three supported sims. That opens the door to shared designs, easier collaboration, and a unified standard moving forward.

Personally, I’m really pleased to have these available. They’re noticeably more detailed and more accurate than the previous generation of helmets, and they raise the visual standard of modern-era mods considerably.

Huge thanks again to Theofilos for the original project — and to everyone involved in bringing it across to other platforms.

GP4: 2011 Mod V1.3 – CSM Menu Image Fix

 

A small but welcome update to the F1 2011 mod — and this one comes courtesy of KerleyF1.

This release focuses on the subtle presentation in the CSM menu interface.

Some of the menu preview images within CSM were either missing or not displaying correctly. While this didn’t affect on-track performance or gameplay, it did leave parts of the menu feeling slightly incomplete, particularly on the Young Drivers Test variant.

KerleyF1 has now resolved that.

All missing preview images in the CSM menu have been created and are displaying correctly, ensuring:

• Full visual consistency across all car/team selections

• Proper thumbnail previews where previously blank

• A cleaner, more polished mod-loading experience

It’s a purely cosmetic update, but these finishing touches help maintain the overall quality standard of the mod, probably the biggest single season mod available in GP4.

Big thanks to KerleyF1 for taking the time to tidy this up.

You can download the updated files here.

GP4: Benetton B197 v1.1 updated

If you’ve downloaded the B197 recently, you’ll know it already features David Marques’ excellent mapping and 4K textures as part of the original release.

While he was preparing the F1 Challenge release (available here), David noticed a detail that deserved a slight correction.

Specifically, the yellow section at the rear of the B197 — an important mark of the colours of Benetton livery — wasn’t matching its real-world reference as closely as it could. Even subtle variations in tone  can be noticeable when compared to period photography or in-game lighting, so David made a quick adjustment which looks a lot better.

All texture files have now been updated to incorporate this change for all races.

GP4: Thruxton by Viking75 - Improved AI and Better Racing

Over the next few days, I have a few smaller updates to share with you. I was going to put everything into one big post, but on reflection, it will be easier to track and find information if they’re split up.

First up: I really enjoyed Viking75’s version of Thruxton — one of my favourite UK tracks. It’s a fast, flowing track where maintaining momentum is everything, and small tweaks to AI behaviour can make a huge difference to how natural the racing feels.

This update focuses primarily on the cc-line. For those unfamiliar, the cc-line defines the racing line used by the computer-controlled cars, but it also influences keyboard steering behaviour. Thanks to the great tutorial written by prblanco over at F1 Virtual, I was able to quickly get up to speed and have a go at creating a new one.

This is my first attempt. I think it’s an improvement, although there’s still room for fine-tuning — particularly around the long right-hander at Goodwood. Church corner remains a great challenge, and I really enjoy the different lines you can take through the Campbell–Cobb–Seagrave complex. The lap times of the computer-controlled (cc) cars are much better now, and keyboard driving feels far more intuitive.

I've also updated the track-side cameras, based off the late 1990s BTCC era. 

Here’s a short video of a quick six-lap race using my WEC mod.
I’m racing on the keyboard. 

Lap one, into the first braking zone — and I’m a little embarresed to highlight it! I brake too late, a slight misjudgment… and I give the Alpine a rather firm introduction to the runoff area. Not my finest moment.

But our car is fine. Keep calm and carry on!

By the end of the lap, there’s more drama! The Penske Porsche ahead is fighting hard after battling the Jota-run Porsche, and as they approach the final chicane it all gets a bit untidy.As a result the Penske-Porsche struggled to navigate the final chicane and I offer a little nudge on the way past.

There isn’t a huge amount of grip in these cars, so the corners are more challenging than they would be in modern F1 machinery around this track. Touring cars here are great fun as well.

I really enjoyed chasing down the pack, setting up an exciting last-lap tussle for second place with the Cadillac. I completed an overtake at Goodwood, only to run wide at Church and hand the position back. Only the final Club chicane to go and now it's the Cadillac's turn to make a mistake. The door is open, and I was able to sprint past on the run to the finish line. An exciting close to an eventful race. 

Next up we have a demo of the external track cameras, here using the 1994 BTCC mod by Huskyman49. Lots of fun in these kinds of cars.

GP4: F1 2025 Mod update v1.2 (CSM) **updated 4th Feb**

F1 2025 Mod compiled by fongu

Here is another update to the 2025 mod. 

Another small update adds some updates for up to the end of the season. This includes performance files by Gitanes, as well as updated track specific weather settings. 

Excalibur has released some excellent additional liveries for the Williams and these have been included in this mod. 

Thanks also to Mailson Teles for exclusively sharing his TV style updated to 2025 exclusively for this mod. There is an option in the CSM menu to enable/disable this, under the TV overlay drop down. 

Thanks to Superman77, the external steering wheels have been fine tuned and the rev lights fit the individual steering wheels much better now. 

The Sound Hardware Acceleration has been updated to a more updated version from GitHub. It's by a number of collaborators. 

The biggest update to this release is by Öggo and thanks to the upgrade of GP4++ to v2.2. This adds modding capabilities to the rear light and blinking under different circumstances. This has now been added to the mod: 

• Now the rain light blinks in wet weather. 
• There is a ERS charging light when you lift and coast. 
• The pit lane light also blinks, but at a different speed to the others. 

Sadly, this does not fix the GP4Tweaker limitation of having a brake light to enable multiple ambient glows, but I have tried to limit it by setting the threshold to 200% brake pressure. It is not full-proof, but also the ERS charging light also comes on when braking at speed. Anyay, GP4++ works seamlessly with GP4Tweaker. 

I hope you enjoy this update. Here's a little video preview of the mod in action.

GP4: ICYMI - January 2026

A new year is under way, and it's time again to catch up with the rest of the 2025 releases in the Grand Prix 4 community. It's been a busy final few months of the year and there's plenty of cool developments by new and familiar authors who have shared their work with the community.

On my side, I have now updated this blog with mirror links to most of these downloads and some on the dedicated 2025 Download Resources page.

Without further ado, let's take a look at what's been released in the community lately.

New Features

GP4++

by Öggo

This combines the Individual Meshes & Textures with the hi-res pitcrews DLL, whilst adding a new feature to have driver specific engineers, and individual meshes for engineers and pitcrews. There are other features now editable directly, such as the NoCD option, enabling advanced car-shader for internal steering wheels, and cockpit visor customisations.

Hi-Res Pitcrew Meshes

by Öggo

Hi resolution pitcrew meshes has been available for a while now, but now Öggo has created a working model for engineers and pitcrews. It is a proof of concept, but still a massive improvement on the original mesh from the original game. This comes with a PSD template, so I look forward to seeing some new skins painted soon.

2012 Cars Add-on (Season Pack)

by SkaningeN

He writes:

"So 2012 it is. And it's quite similar to the 2011 Add-on, but this time I decided to bring you an whole season set of cars in one package. Even the versions I have not edited so you can easily make your own mod if these are the cars you want to use. All versions (I Think) is included in this pack, I've done my best to spot differences, correcting mistakes on existing ones and adding missing versions. Most cars are converted from F1CM by Josekast, with a select few from Soulbringer, Hega and RSCT."

2012 Helmetset and Shapes

by SkaningeN

He writes:

"The 2012 helmetset now with seperate helmet shapes. This helmetset have gotten some tweaks and now also gotten the correct helmetshapes for all drivers. I've added some missing helmets, fixed some others, fixed the alphalayer on some and added new versions that seemed to be missing.

All helmets from the 2012 season (that I know of) is included in this pack and are painted to fit the correct helmetshape. And I've done the best I can to make sure each helmet has the correct visor tint for the right races. But in most cases, you can decide yourself. You can run all helmets with individual shapes or you can use all helmets with only one shape for all. But if you only use one shape, some textures will not fit properly, most cases the visor tear offs and the new visorstrips on the updated shapes."
