I had originally made a 1:1 replica but this personal take looks quite sexy ingame.
To install make sure you have a skin directory folder in your rF2. Example: "C:\Users\You\Saved Games\rFactor 2\UserData\player\Settings\Civic_BTCC_Car\CIVIC_BTCC_7"
You can create that folder from the ingame Tuning screen (where you select your car) by clicking on the lower right "Create Directory." Just place the .mas file in there .
ps: I created the Dunlop joke sponsor myself, Duopop too.
pps: Feel free to extract the individual textures for your own use.
