I don't understand much about physics, but you have made a car that could not be driven, now possible. Curiously, half an hour ago I found the original car, after installing it and seeing that it could not be driven and that it is from 2015, I left it as impossible; I enter racedeparment and I see that a few minutes ago you have uploaded this FIX. My most gratifying congratulations.
You need to install the original mod and copy the files to the vehicle and replace it
