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.

TC: - I recommend the TC6.
      - TC5 for the T1 and for the Corkscrew
      - TC4 for the last corner

HotLap/Qualifying lap adjustement:
- Target psi tyres 26.9-27,0
- Rear Toe: decrease 1-2 clicks if you want more turning OR don't touch
- Rear Antiroll Bar: increase 1 click if you want more turning OR decrease 1 click if you want more stable
- Rear Ride Height: increase 1-2 clicks if you want more turning OR decrease 1 click if you want more stable but understeer appears OR don't touch

Race adjustement (advice):
- Target psi tyres between 27,1-27,2 
- Front Antiroll Bar: increase 1 click if you want more stable OR don't touch
- Rear Antiroll Bar: decrease 1 click if you want more stable OR don't touch
- Rear Ride Height: decrease 1-2 clicks if you want more stable but understeer appears OR don't touch
- Front Brake Ducts: it depends on the temperature
- Rear Brake Ducts: it depends on the temperature

My best lap with this setup: 1:21.185 (on a mega lap, there is the possibility of doing .0 high, so you can improve so much my time)

Good Luck and Have Fun.
