Ferrari’s strict licensing. Don’t worry everything is fine, they just limit the stickers available for the cars.
There are two ways to overpass it :
- Any sticker shared by the community is allowed.
- Add the « forbidden » decal to your favorites (like the Michelin decals which are not possible on the Ferrari). They won’t be visible in the main section BUT they work if you look at your favorites selection.
Always been a thing as far as Ferrari is concerned, I personally think it's stupid esp when some of their own decals in game are reported
because not officially licence to PD.
