I just got crazy with the TC settings for this car.
Definetly the chaps on teamspeak were correct that the lower the value selected (1-5) the more the TC is used.
What I found weird is how the TC works on this car, as when I set it to the lowest value the acceleration was really really bad. I do not recall to see this behavior on TC before. Is it like this for this car only or the same for the rest?
