This mod adds Ford RS200 to the Car Mechanic Simulator 2018.
Things just got funky, now with 2 versions, which means new parts of course. The rear left fender is the thing you’re looking for. Also I know the mighty wings don’t open with the trunk.
How to install this mod:
Download the file. Unzip the archive. Copy the folder to the folder “Car Mechanic Simulator 2018/cms2018_Data/StreamingAssets/Car”.
Avoid double folders, look carefully so that there is a folder with the name of the car and its files.
