Rally 'license' - you can't change any kind of car setting when doing licenses (apart from ABS and TCS - some people call these driving aids though, others don't), you can only change driving aids in options. Even then, sometimes, with certain licenses these are restricted too.
Could you start giving some details of exactly what you're trying to do, being vauge doesn't help people giving you an answer that'll help you because it's hard to know exactly what you're talking about.
What license is it - what car you using and maybe provide the link to the youtube clip you're talking about - that'd be very helpful.
Thanks...
