For the full experience with other and my car skins, this mod remove the original car numbers. Only the skin numbers will be visible, just look to my BMW skins to see what i mean.
In addition this mod remove the ability to get scratches during the race. The car only become dirty and breaks down on accidents, but no scratches.
To install just copy the "cars" folder to your Grid Autosport folder und overwrite the existing file. A backup file is included.
