The UI files included modify the car name and description to reflect the real name of the car. This is for version 1.0 of the URD mod, I will try to keep this up to date as URD release new versions.
How to install:
- Extract to the URD Michigan GTD car directory (defaults to %ProgramFiles(x86)%\Steam\SteamApps\common\assettocorsa\content\cars\urd_michigan_gtd
- Overwrite all files where prompted
Note: These files modify the car name and brand in the UI only, it will not alter the in-game name. Because of this, you should not have any issues with data mis-matches when joining online races, but I cannot make any guarantees. If you wish to revert to the originals, just copy the UI folder from your original URD archive to [your AC folder]\content\cars\urd_michigan_gtd\ overwriting all files when prompted.
