Assetto Corsa Evo: Selecting Cars and Balance of Performance

Whether you want an all-GT3 grid, a one-make cup, or a varied mix of classics, you decide which cars other players can choose on your Assetto Corsa Evo game server. You can also balance individual cars by adding weight and limiting their performance. This guide shows you how to configure the car selection and includes the complete car list with performance ratings and categories.

All cars are listed in the server_launcher.json file in your server's main directory, under Event in the Cars section. Open the file in the Configuration tab using Edit directly, or in the Files tab. When you start the server for the first time, ZapX creates the file and enables all cars.

Each car has its own entry. Here's an abbreviated example:

{
  "name": "preset_m4gt3_mech_1",
  "display_name": "BMW M4 GT3 Evo - GT3",
  "IsSelected": true,
  "is_selected": true,
  "Ballast": 0,
  "Restrictor": 0,
  "PerformanceIndicator": 21.2,
  "P1": 1,
  "P2": 0,
  "P3": 0
}

For fair races, everyone should drive in the same class. You can usually identify the class from the display_name. Here are a few examples from the current car list:

Enable only the cars in your chosen class and disable all the others.

In the official Assetto Corsa Evo server software, you can select cars with similar performance using a Pi slider. You can find the value for each car in its PerformanceIndicator entry and in the Pi column in the table below. Cars with similar Pi values have similar performance. If you want a mixed grid where the cars are still closely matched, for example, enable only cars with a Pi between 10 and 11.

These are the cars included in the server_launcher.json file that ZapX creates when you start the server for the first time. The category, era, and powertrain correspond to the P1, P2, and P3 values in each entry:

• Category (P1): 0 Road, 1 Race car, 2 Trackday
• Era (P2): 0 Modern, 1 Classic, 2 Youngtimer
• Powertrain (P3): 0 Combustion engine, 1 Electric, 2 Hybrid
