I recently purchased 3 different Indycar Assetto Corsa 2021 MODs from Virtual Racing Cars, Apex Modding Group and Racing Sim Studio. The best Indycar MODs are those made by Vitor "Shadow" Souza which have full detailed liveries and helmets for each track. Unfortunately, Vitor didn't finish yet the full 2020 season, only part of which I have converted to GP4 and the MOD is available to download here: [

He doesn't have a plan to release the 2021 MOD and that's why I started to make the 2021 MOD using the cars from the Racing Sim Studio because it has skins for all cars and teams that are available at Racedepartment. For sure, they won't give permission to convert to GP4 and if I decide to release MOD 2021 it will be through PM. Besides, there is no full set pack of the helmets, just a few available, which I'm not happy about. If anyone wants to make the helmets would be great.
Anyway, here you have the car for the oval tracks, some quality is always lost to make a car with 65k faces only as the original made by RSS has 230k. Anyway, this is the best I can do with my limited skills and let's see what will happen regarding a future release.
