Hello! I've seen a video online where people used launch control and 2-step on demo cars. Unfortunately that video was for the version 0.6t or 0.6r, and i can't find still working versions of the mod. Does anyone have a still working version of that mod, or is it completely off?

Pretty sure that is a external tweak/hack program, hence it is not allowed in the game (and also hence why its not been carried over)
