Assetto Corsa - How to Change FMOD Soundbank's GUIDs
Please, don't forget to do this every time you make a new project based on Tatuus Formula Abarth example. Otherwise there are could be some problems (if two cars in one race have same GUIDs, they will be have the same sound).
Also don't forget to remove unused samples to make .bank-file smaller, but it's not that necessary.
