Assetto Corsa includes a wide selection of car skins by default, giving players the freedom to customize the appearance of their vehicles. Using this method, you can also change the skins of AI racers and other cars that appear in races. The ChipHead Panel provides an easy way to view all available skins, including custom ones.
