try this .
i'm doing 58 low on qualy and 59 low with full tank.
I had a weird tyre wear during a 45min race but is probably because of me
tell me how you feel about it.
Update:
Ah almost forgot bruh! that's my very personal Porsche 991.2 Setup .
For the McLaren i suggest you to play around a little with the Aggressive ; in other words the understanding of the way the McLaren brakes play a major part in her "F1" grip level
As personal note,
i'm not a top notch driver, in the McLaren , honestly can't exploit the grip of this car...sadface
