BMW M4 GT3 REDBULL RING

AC EVO only creates a car/track folder after you save a setup there once. To make it appear:

1. In game, pick the car (BMW M4 GT3 Evo) and track (Red Bull Ring), then go to Vehicle Setup.
2. Click Load/Save (bottom right).
3. Type Default and press Save - you don't need to change anything, this just creates the folder.
4. The folder now exists at the path above. Drop the downloaded .carsetup file in, and it'll show up in Load/Save in game.
