I did not want to make a new topic, but the clutch.
In real life, when you release clutch and hold it in the right position(depends what car you have) , car does not stall out like in lfs, it starts to move.
I´m not the right guy to talk about it because my PB is 1:16.150
But first you are using keyboard, second your driving line is not greatest. Your first sector should bemaximally 0:24:500 to get lap time somewhere around 1:14:700.
That´s what i think. Correct me when i´m wrong about something.
