Tracks Stupid AIs at le mans 1967

[qoaks]

The AI cars, especially the ford GT40 mkII tend to overshoot the braking zone at "Le grand circuit 1967" and jump at the mulsanne hairpin. I don't know if this is related to the track "Le grand circuit 1967" by Terra21 found here at racedepartment or to the car/cars. I have noticed that they jump way less when I lower the strength to 60-70%, but at that point they are very slow and it's no fun. I tried to see if they would build up some experience by launching a 25 min practice session and a 8 min qualifying, but that did help when it came to the race. Any tips on how to fix this, and have anyone had a simular problem?
