As
@Pesselles said if you 'save best lap' replay each time you get a PB then you can go to the ghost settings and load it...
You can then also set it a certain distance in front of you to stop it from being in your way, and then chase it...
I tend to start with an alien ghost at 0.3 ahead to see braking points and then as I get quicker I reduce it to 0.2 to better follow their lines through corners.
If you watch
@Tidgney guides, he will mention what is generally the optimal shift point for each car, some prefer short shift and some are better to rev right to the end.
Downshifting also has an effect on weight shift so sometimes is also better to hold A higher gear longer when braking instead of shifting down quickly.
I tend to stick with ABS weak unless I am getting lock up, only then will I switch to default.
TCS I try not to use but some cars I need to and tend not to go above 2 if possible.
CSA is sometimes a blessing in disguise, I tend to use this now since the 1.50 update when I'm on the controller.
The force feedback sliders will not affect the controller at all unless you are using motion steering.
I used to always leave the sensitivity slider at 10 on controller and wheel but again, since update 1.50 I tend to have it at -2 near enough all the time as I get a smoother input and less snap oversteer.
Hope this helps you
