Yes, I've had a look in the code and it looks like that should work.
How to use it:
- create a text file in your data\script folder
- add a line in the text file like /ff 30 (whatever force value you want)
- rename the text file SKINID.lfs (Skin ID of the mod you want to set)
Let me know if I've missed something. I know it's not super convenient but it can help for mods you use often.
By the way, in the new LFS there is something about a power steering setting, trying to do it a more realistic way. In code it's simply an amount to reduce the FF, and can be adjusted in the setup, if the car has power steering. But I'm not sure yet how to make sure mod creators set a suitable value for power steering. Anyway going off topic.
By the way, the SKINID.lfs script is run *after* the one like "road.lfs" or "paddle.lfs" etc.
