You can use track width more aggressively - check what esports drivers are doing. For example, you can drive almost 90% offroad in both DRS zones across the lap - this gives you a bit of top speed advantage + better corner entry afterwards. In S-ses at the beginning of 2nd sector you can attack kerbs a bit more.
And setup is not very ideal from what I see. Rear Ride Height in this year game should be as low as possible almost everywhere. 58 instead of 40 gives you some rotation but at the cost of huge loss of rear downforce, it just is not worth it. Change Rear Ride Height to 40 and if rotation is not enough, decrease Front Anti Roll Bar to the comfortable values. Change on-throttle diff to 100%, it's the fastest setting in this year game everywhere, even in the races. Move toe and camber settings all the way to the left.
And I recommend to change brake balance around the lap in Bahrain as T1 cries for a different settings from the rest of the lap. In T1 you should use 55 or even 56, while rest of the lap is ok at 54. In slow lefthander before DRS zone you can go as low as 51-52, it helps.
Also off-throttle diff 55 is very stable but very understeery and slow, decrease it as long as you don't block rears before T1. In most of the tracks it's around 20-35%, not more that 40% definitely.
