This car is great but way slower than the BTCC official cars maybe the tyres are the problem?Could it be updated?

the sentence you wrote doesn't mean anything clear... are you speaking about the way to add other cars with customized painted skins? If yes the procedure to be followed depepnds of the way it works in rFactor2, not by a specific mod. I suggest to read the documentation released by S397 like https://docs.studio-397.com/users-guide/how-to-paint-a-car-with-the-new-material-system

Thanks for the help with your mod .....

I've got a problem when adding a car :no skin visible.

good mod this well done.

Fantastic mod one of the best.

Thanks .Cuore Sportivo as they said long ago...
