At the moment it is not possible to do it from our new official repositories because it is unverified licensed content, but you can do it ‘by hand’ by downloading from the old repository and putting them inside the ‘cars/models’ folder in the settings folder (in ‘/home/[username]/.speed-dreams-2’ on Linux, or in ‘C:\Users username]\Documents\speed-dreams-2.settings’ on windows):
Take a look on this links:

hey, i tried downloading cars and tracks from the links above and i followed you instructions on where to keep the files (i extracted the .zip into the 'speed-dreams-2.settings' folder) and when i tried to download it in the game, it said "failed to remove file: permission denied". id really love to play on the other cars and tracks. but overall amazing game!. btw im using a windows 7 32-bit pc right now.
