hello all ..
I am brand new in using LFS and I want to know can I change the car's parameters such as the weight and the initial speed and others in the demo of LFS ?
thank you so much for your help

Well.. If you where S2, I could help you, It's called LFStweak, I believe, But you break something with legalities if you use it on demo.

In short just don't use it, But you can look into it, Like on youtube.

like paws said, you would have to be at least s1 licensed to use the program you do this with.

the program is called LFStweak.

Hasn't the license check been removed from LFSTweak like... quite a long time ago? Anyway, google for LFSTweak and try it out, you won't get any better help than this because of the forum policy...
