Thanks for your fast response, to be honest my problem is not that I am driving too fast for the AI, but like I said the extreme variety of skill regarding the AI. When I set difficulty to f.e. 100, the fastest driver is way too fast for me, when I set AI to f.e. 85, I can have a lot of fun with the fastest AI but the weaker ones are way too slow and are overlapped whithin 3 or 4 laps. Thanks anyway for your efforts, like I said I enjoy this Mod a lotNo way to balance the AI, some AI's have lower skill level, consistency, etc., naturally some are faster than others. I'll look into adjusting the difference in pace between them.
If you are beating the AI way too easily then you can enable restrictor and ballast in the driver profile menu.
