How to install Assetto Corsa EVO car mods

AC EVO car mods are shared as one packaged file, a .kspkg. Installing one is a copy-paste into your game's mods folder. Here's the whole process, the two file formats you might run into, and what to check if a car doesn't show up.

Quick version

  1. Get the mod's .kspkg file (download it here, or someone sends it to you).
  2. Drop it in Saved Games\ACE\mods\ (create the folder if it isn't there).
  3. Launch AC EVO. The car appears in the garage.

No SDK, editor, or Steam mod subscription needed. The .kspkg is self-contained.

Installing a .kspkg

  1. 1

    Get the .kspkg file.

    Download it from EvoMods, or have someone send it to you (Discord, Google Drive, etc.). It's just a single file.

  2. 2

    Put it in your game's mods folder.

    C:\Users\<your-username>\Saved Games\ACE\mods\<mod_name>.kspkg
    • If Saved Games\ACE\mods\ doesn't exist yet, create it. (It appears once AC EVO has been run / any mod has been added.)
    • The .kspkg goes directly in mods\, not in mods\content\cars\.
  3. 3

    Launch AC EVO.

    The car should appear in the garage / car selection.

What you need

  • AC EVO installed (a matching game version; see the note on versions below).
  • No SDK, no editor, no Steam mod subscription. The .kspkg is everything.

Downloaded from EvoMods?

Mods here download as a compressed archive (.zip, .7z, or .rar). Extract it first. Inside you'll find either a .kspkg file or a loose mod folder (see the two formats below), then follow the steps above.

The two file formats

The AC EVO editor exports a mod in one of two forms. As an installer you'll almost always use a .kspkg; the loose folder is mainly a creator's testing format.

Form What it is Use it for Where it goes
Loose folder
(unencrypted) 		The raw mod folder, copied as-is Your own testing while building Saved Games\ACE\mods\content\cars\<mod_folder>\
.kspkg
(encrypted) 		One packaged + encrypted file Sharing / release Saved Games\ACE\mods\<mod>.kspkg

The loose folder is editable and unencrypted, which is great for the editor↔game loop but not for distribution (anyone could copy or alter the assets, and a whole folder tree is clumsy to share). The .kspkg is the real distribution format: one encrypted file, assets protected, easy to send.

Car not showing up?

  • Confirm the .kspkg is in Saved Games\ACE\mods\, not mods\content\cars\.
  • Make sure the mods\ folder exists and you've launched the game at least once.
  • Check your AC EVO version matches the mod's (see below).
  • A loose folder used for testing goes in mods\content\cars\<folder>\, not directly in mods\.

A note on game versions

AC EVO is in early access and updates frequently. A mod is built against a particular game build, so an update can stop an older mod from loading until its creator re-exports it. If a car that used to work disappears after a patch, a version mismatch is the usual cause. Check the mod's page for a build that matches your game.

Only install files you trust

A .kspkg is encrypted, so you can't inspect its contents before the game loads it. Stick to downloads from EvoMods or creators you know and trust.

For mod creators: packaging your car

Releasing a mod is one step in the AC EVO editor:

  1. In the editor, run the encrypt function on your mod folder, and it produces a single .kspkg file.
  2. That .kspkg is the whole car, encrypted and self-contained, so you can hand someone just that one file.
  3. They drop it into their Saved Games\ACE\mods\ folder (not mods\content\cars\) and launch the game. No SDK/editor needed on their end.

Premium builds are always distributed as the encrypted .kspkg; community mods may come as either a .kspkg or a loose folder.
