This is what I used to have when it ran a 7:16 with 2 mistakes.
Now I increased the ride height by a few mm all around, brought the dampers (extension) to 5 and 6 and dampers (compression) to 5 and 4.
I increased the anti-roll bar stiffness to 4 and 4.
Did a test lap and the car ran a 7:09 with one small mistake.
Without any mistakes, the car can probably do a 7:02 - 7:05 with this setup.
