MX-5 ND Cup - Oulton Park 15 min race

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 (Mazda MX-5 ND Cup) and track (Oulton Park International), 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.
