How to Install New Cars for GTA 5 — Add-On Method

If you want to add new cars, planes and helicopters, boats and motorboats, motorcycles, and other vehicles to GTA 5, you will often need to resort to "Add-On versions." In this guide, we will explain in detail how to install cars in GTA 5 using the Add-On method.
Adding vehicles to "GTA 5" using the Add-On method has its pros and cons. The pros include that the car, boat, or plane will be added only for the player, and other NPCs will not be able to use it. The downside is that not all modifications can be added this way. So before installation, make sure the mod supports this function.
Download the Necessary Scripts and Programs
Before adding any vehicle to the game using the described method, players first need to download and install separate scripts and programs.
Script Hook V
Script Hook V is a library of files that allows you to use custom GTA 5 script functions in user .asi plugins.
- Download Script Hook V.
- Copy ScriptHookV.dll into the root folder of the game (where GTA5.exe is located).
- If you need an asi plugin (trainer), copy NativeTrainer.asi into the game folder.
- To load individual asi plugins, you will need to separately install the asi loader. To do this, move the file dinput8.dll into the root folder of the game (if you have used asi plugins before, delete the file dsound.dll).
Script Hook V .NET
Script Hook V .NET is a plug-in asi plugin that allows you to run scripts written in any .NET language in the game.
- Install Microsoft .NET Framework 4.8 (or a later version) and the redistributable package Microsoft Visual C++ for Visual Studio 2019 (x64).
- Download and install the latest version of Script Hook V (see previous section).
- Download Script Hook V .NET and copy the files ScriptHookVDotNet.asi, ScriptHookVDotNet2.dll, and ScriptHookVDotNet3.dll into the root folder of the game.
Add-On Car Spawner Menu
Download the Add-On Car Spawner Menu and copy the Scripts folder into the GTA 5 game folder.
OpenIV
OpenIV is a free set of tools for modding Grand Theft Auto 5 and other games, allowing you to view and modify game data.
You can download it from the official website. If the site is not working, here is the offline version.
How to Set Up OpenIV
- Open the OpenIV application;
- Select "Grand Theft Auto V – Windows";
- Set the path to the GTA 5 game folder;
- Click "Continue".
Note: When the application detects the game and opens the main interface, be sure to click on "Edit Mode".
- Click on the "Tools" button;
- Select "ASI Manager";
- Here you can track the necessary components for the program. If any of them are still not installed, press the "Install" buttons one by one, as shown in the screenshot below.
Please note: During the installation of the ASI Manager in OpenIV, the program will offer to create a separate folder for modifications named "mods." Be sure to do this, as it will allow you to install mods without compromising the integrity of the game files. Additionally, the user can remove any mods they are not interested in at any time.
How to Set Up the Mods Folder
- In the menu on the left, find the update directory and follow the path: "x64/data/dlcpacks/mpairraces";
- Find the file dlc.rpf and right-click on it, then select the action "Copy to 'mods' folder";
- Return to the update directory and select the file update.rpf. Similarly, copy it to the mods folder.
How to Add a Car to GTA 5
Note: Modders usually provide detailed instructions for the add-on. Be sure to read it before installing cars, planes, boats, and other vehicles.
Main Method
Using the example of the 1953 Ford Mainline Fordor Sedan mod.
Enter the game and create the vehicle named mainline53 using a trainer.
Additional Method
It is worth noting that this method only works for installing single modifications. If you want to add a collection of cars or other vehicles, you will need to use additional programs and scripts.
How to Add a Collection of Cars. Why Does an Error Occur During Installation?
On our website, you can also find modifications with ready-made car collections that are installed using the Add-On method. However, often when installing in the standard way, a number of errors appear after launching the game:
- SKRIPT HOOK V CRITICAL ERROR (FATAL: Unknown game version);
- ERR_FIL_PACK_1 (Game error. Please reboot and restart the game);
- ERR_MEM_EMBEDDEDALLOC_ALLOC (Out of game memory. Please reboot and restart the game).
To avoid this, players need to install additional software and make a few adjustments. There's nothing complicated about it — the whole process will take you no more than five minutes.
Gameconfig for Limitless Vehicles
Gameconfig for Limitless Vehicles allows you to store a wide range of vehicles and adds various driving modes to the game. With this modification, you can also customize your cars.
- Download Gameconfig for Limitless Vehicles.
- Unpack the archive to any convenient location on your hard drive.
- Open the OpenIV application and go to the path "update/update.rpf/" and copy the contents to the "mods" folder.
Go again to the path "update/update.rpf/common/data" and find the file gameconfig.xml there. Make a backup of this file anywhere on your PC. Then do the following:
- Open the root folder of the game.
- Find the application
GTA5.exe
, right-click and select "Properties". - Go to the "Details" tab and track the game version.
- Return to the unpacked files from the downloaded archive and find your version in the "Old Versions" folder.
- Find the folder named "1x traffic 1xpeds (Stock Traffic (Means Gta base))" or "1x traffic 1xpeds (Means Gta base)" depending on the game version.
- Open OpenIV and replace the original gameconfig.xml file with the file from the archive.
Packfile Limit Adjuster
Packfile Limit Adjuster helps eliminate the ERR_FIL_PACK_1 error (Game error. Please reboot and restart the game). Just download the archive and unpack the files PackfileLimitAdjuster.asi and PackfileLimitAdjuster.ini into the root folder of the game.
HeapAdjuster
HeapAdjuster helps solve the problem with the ERR_MEM_EMBEDDEDALLOC_ALLOC error (Out of game memory. Please reboot and restart the game). Copy HeapAdjuster.ini and HeapAdjuster.asi into the root folder of the game.
I Followed All Instructions, but Errors Still Occur
If after the above actions you still encounter one of the previously mentioned errors, it is usually because many unoptimized mods are installed for the game.
You can perform the following actions:
- Open the root folder of the game and find the HeapAdjuster.ini file.
- Right-click and select "Open with," then "Notepad."
- After the parameter "HEAP_SIZE =", enter the value 1000, 1200, or 1500 (depending on the amount of installed RAM).
Do not set the value above 2000, as this will inevitably lead to crashes and other errors.
If this method also did not help eliminate the error, then you will have to remove the unoptimized modifications that were previously downloaded.
