How to Install Custom Cars, Tracks & Skins on Your Assetto Corsa Server

Assetto Corsa's modding community has built thousands of custom cars, tracks, and skins. This guide covers how to install them on your server, and what to tell your players so they can join without a checksum error.

Content Directory Structure

Custom content is read from two directories in your server's root folder:

Installing a Custom Car

1. Download the car from a trusted source. The download should contain a single folder named after the car's internal ID, for example my_custom_car.
2. Connect to your server. For a small file you can use the Files tab in your MintServers panel; for a large car with many texture files, an SFTP client is faster. See our SFTP connection guide if you haven't set this up before.
3. Upload the entire car folder into content/cars/, so the result is content/cars/my_custom_car/ with its data and skins subfolders intact.
4. Open cfg/server_cfg.ini and add the car's folder name to the CARS line, separated by a semicolon:

CARS=ks_ferrari_f40;ks_bmw_m3_e30;my_custom_car

5. Open cfg/entry_list.ini and add a new grid slot for the car, setting MODEL to the car's folder name and SKIN to a valid skin folder inside its skins directory:

[CAR_4]
MODEL=my_custom_car
SKIN=default
SPECTATOR_MODE=0
DRIVERNAME=
TEAM=
GUID=
BALLAST=0
RESTRICTOR=0

Full detail on every entry_list.ini field, including locking a slot to a specific driver, is covered in our server configuration guide.

Installing a Custom Track

1. Download the track. The download should contain a single folder named after the track's internal ID, for example my_custom_track.
2. Upload the entire track folder into content/tracks/, so the result is content/tracks/my_custom_track/.
3. If the track has layout variants, keep the variant subfolders intact inside the track folder (for example content/tracks/my_custom_track/full/ and content/tracks/my_custom_track/short/).
4. Open cfg/server_cfg.ini and update the track fields:

TRACK=my_custom_track
CONFIG_TRACK=full

Leave CONFIG_TRACK blank if the track has no layout variants.

Installing Custom Skins

Skins live inside the car's own skins folder, one subfolder per skin.

1. Download the skin. It should be a folder of texture files, for example my_livery/.
2. Upload the skin folder into content/cars//skins/, so the result is content/cars/ks_ferrari_f40/skins/my_livery/.
3. To assign it to a grid slot, set SKIN=my_livery on the matching [CAR_N] block in entry_list.ini.

Once your content is uploaded and your config files point to the right folder names, you're ready to race. If a mod still won't load correctly, no worries! Just open a support ticket and our team will take a look.
