This pack includes 10 skins, of which seven are created by me and three are from the game, but with driver information added. I chose one driver for each car to avoid clustering names on the leaderboards of races against the AI. They were initally intended to replace the default red skins with their same number. If you want, you can disable the default skins number 9, 19, 21, 22, 23 and 24 with Content Manager, since my pack includes all of these with different colors and / or new driver information.
The non-red cars have custom colored leather seats. They aren't meant to be historically accurate, I just changed them to match my personal preferences. If you don't like the new color, just delete the leather_2.dds file and the classic red will be back.
