Noob question: how/why do you use TC, BB, Turbo and roll bar settings.

[Andy Muir]

I'm not really a motor enthusiast but love racing simulators. Despite having a blast, I consequently have no idea what have of the tools available to me do.

I thought roll bars were safety features! Why would you adjust them?? Mapping engines?

Would it be possible to explain what the cockpit adjustable settings do and why you might want to change the settings please i.e. how each settings affects driving and use cases.

And the same for... roll bars?

Thanks!
