What is your current pb and what is your planned lap time for near future.
A lot goes into the way you control the car, most of it boils down to your skill, the controller you are using and the setup.
I personally think that the best way to improve your lap times is to really get comfortable with the racing line and to analyse the replays of quicker guys.
