Hi, There are different rules in the differents real life series that allow different driving aids. There's no problem about that with rfactor2 actually but one thing that may help is an option on the server that read in the mod wich aid are allowed in the series and unlock it accordingly on the server. I'm not sure if i'm clear enough.
Well misunderstanding certainly! I already host a server NO what i mean , what i would , would be an option on the hosting menu where you can 'allow all real aids available in real life car/series' that would be defined in the mod, if you host a mix of multiple series, you could allow abs on gt3 cars for exemple but disallow it for the prototypes.
