This thing asked about previous comment, answer is this: I can see that track grip is too low, please check surface.ini file from data folder, there's grip value FRICTION=0.95 for ROAD and ASPHALT but what is the most weird thing is that the pitlane friction is 0.99 so there's best grip in pitlane???, that 0.95 for dry track surface is way too low,
I normally change road friction to 1.15 to make car feel more realistic but not too easy to drive, less than that is way too slippery in any car, like ice. I really do not understand Kunos way to add grip less than 1. I live in Finland and I know what the difference is between icy road and dry & hot road grip very well.
