To add a custom car to your FREAKHOSTING Assetto Corsa server, upload the car’s server data (its folder with data.acd) to content/cars/ in Files, add the car’s folder name to CARS in cfg/server_cfg.ini and add [CAR_x] slots for it in cfg/entry_list.ini. Restart the server. Every player needs the same version of the car on their PC, or the server rejects them.

​
Before you start

  • Install the car on your PC first (assettocorsa\content\cars\<car folder>) and drive it offline once.
  • Note the car’s folder name, for example my_gt3_car. That is the car ID.
  • Make a backup.

​
How to add a mod car to your server

1

Get the car's server data

Build a server preset with the car in Content Manager and click Pack. The pack holds the server data for each car, including data.acd. See Content Manager server presets.
2

Stop the server

Stop the server.
3

Upload the car folder

In Files, open content/cars/ and upload the car’s folder. Keep the folder name the same as on your PC.
4

Add the car to CARS

Open cfg/server_cfg.ini and add the car ID to CARS, separated by ;:
5

Add car slots

Open cfg/entry_list.ini and add one [CAR_x] section per grid slot for the new car. Number the sections in order with no gaps:
Set SKIN to a skin folder name from the car’s skins folder, or leave it empty. See entry_list.ini explained.
6

Start the server

Save both files, start the server and check the console. The lobby line lists the cars the server offers.

​
Why players get kicked with a mod car

The server compares each player’s car data with the data.acd on the server. If the player has a different version of the car, they can’t join with it. Share the exact download you used, and upload the new server data whenever you update the car.

​
Cars already on your server

The Kunos cars are installed in content/cars/, for example bmw_m3_e30, ks_mazda_miata and ferrari_458. Open the folder in Files to see the full list. Cars from DLC packs need the matching DLC on players’ PCs.

​
Frequently asked questions

​
How many cars can I put on the server?

As many as you have slots for in entry_list.ini. MAX_CLIENTS limits how many players join at once, and it can’t be higher than the track’s number of pits.

​
Why is my new car not offered when I join?

Check that it is in CARS, that entry_list.ini has a free slot with MODEL set to it, and that the folder name matches exactly, including lowercase letters.

​
Can I remove the default BMW?

Yes. Remove bmw_m3_e30 from CARS and change or delete its [CAR_x] sections. Renumber the remaining sections from CAR_0 without gaps.
