Ahm, dont know exactly but should be in any of the files of the frontend folder.
Same procedure after you found it as with the other pics.
Your Safety car question:
I heard something of in the database... But it hadnt any effect in my eyes.
In "tracks" (i think thats how its called) (in the database) you can set how often the sc can come in every specific race. if you put it to 1, there could be no safety car or max. 1. 2 arent possible. Check out, if there is any to zero and change it to a higher number.
But that wont change very much. There was a higher safety car chance mod out there, very good work. A lot of changes are need, so i would install it instead of trying on your own.
If there is something which replaces some of your previous changes, you have to retype them (if the database is replaces and you want the qualfiyng abiltiy of driver xy different, you have to redo it in the saftey car mod database.
