Okay, here's my setup:
Front Wing Angle: 8
Rear Wing Angle: 8
Braking Balance: 50/50
Pressure: High
Brake Size: Large
Front-Antirollbar: 1
Rear-Antirollbar: 11
Front Ride Height: 1
Rear Ride Height: 1
Front Spring Stiffness: 11
Rear Spring Stiffness: 11
Gearbox in km/h: 142, 168, 199, 230, 264, 300, 343
Camber Front: -3.50
Camber Rear: -1.50
Toe Front: 0.15
Toe Rear: 0.50
It seems a little extreme, and it took a while to get used to, but I used it the instance when I the same setup get a 1:16 in a video. And Ive been doing a lot better than the default setup I was using before. The main part is, I put consistent laps out with no wrecks at all. I haven't come close to 1:16, but getting 1:22 every lap is satisfying enough for now.
