I tried unpacking the data and I tried using AC quick car tuner.
The unpacked .ini files are just gibberish. And AC quick tuner cannot edit the files as I get an error that says car won't be loaded, check your data folders as there's no compressed data for this car. I assume it just cannot...
Specifically, I was wondering about the Factory Five Racing Type 65-R Kit car?
Which looks similar to a Daytona Coupe with modern suspension and aero.
or are Kit Cars not done as they aren't a consistent "model" (too much variation from car to car).
