4 x plates.
I will be adding to these plates in the near future.
Copy the Plate_D.dds and Plate_NM.dds into your chosen skin folder within the 'Skin' folder of your car. If you think you need to keep the previous Kunos plates save them first elsewhere.
Please note any Integrity validation of your Assetto Corsa files through Steam will replace the old Kunos plates.
