You need to be more focused. Take better lines, brake in time so you can do the throttle part sooner. You need to know the braking power of your car and how long you need to brake to desired speed. If you can be a spectator from the AI point of view so you can see when they are braking, how fast are they at certain sectors.
I used an FOV calculator and changed my FOV from the default 86 down to 61 and that alone made a huge difference. As noted in the title of the vidya, it was my first drive. Ever. I had just installed the game, started up a quick race and hit record. dinex86.github.io/FOV-Calculator/
