so yes there in the options we currently can adjust the ai difficulty and the aids as well as gear change options
the 3 aids ( TC,ABS, stability control) can be mapped to a wheel or controller useful if you race turns wet quickly i've used the function for tcs a few times.
i'll have to double check but you may be able to adjust the amount of slippage as well.
i also have ac but ac suffers in a few areas such as ffb. it also seems more forgiving compared to PCARS and rfactor 2. however it could also be my driving force gt giving me this effect.
