First of all, I want to point out that the setups are pushed to the limit while having a rather stable GT3.

Engine rpm: shift between 8100-8200 (98% of the time, the 6th will not be used)

TC: - I recommend the TC6, it does a good job without slowing you down
      - TC5 for fast corners
      - TC4 for exiting slow corners like hairpins

I tend to lower the steering ratio because I like to have a more responsive GT3 when I turn my wheel while putting very little angle.
Don't hesitate to raise the steering ratio by 1-2 clicks if you are used to playing with more steering ratio.

Be patient with the Mustang. This setup feels heavy, but it makes the Mustang excellent and stable.

Race adjustement (advice):
- Target psi tyres between 27,1-27,3
- Rear Toe: decrease near to or 0
- Rear Antiroll Bar: 9 > 8
- Rear Ride Height: 76 > 75 or 74

Good Luck and Have Fun.
