This is my setup for F1 2010 Lotus in Catalunya Spain - Dry.
Time Trial 1:21.684. Only Assists were Corner Racing Line and Automatic Transmission. G27.
Qualified 5th in Dry conditions with a 1:22.6XX. I sped up the qualifying in the last 5 minutes and went from 1st to 5th.
7th in a Dry Race, Legendary AI. I got to 3rd by the first corner and stayed there. I pitted on lap 8 to avoid being held up in the pits for 17 seconds.
I hate Over-steer so this is set up to boot it early out of the corners.
I set it for fast so that you can get some of the speed on the straight. But to compensate for the over-steer, I gave it more rear wing and softened up the rear suspension to soak up the bumps better. But sets up under-steer so I gave it a little more front wing for those fast corners.
The big issue is the last chicane. Slow right down, don't hit the ripple strips at all. Cut in sharp on the first corner and then accelerate out and go wide to get a good run onto the straight. If you do hit the ripple strip, only hit the second one. Roll over it and wait for the car to settle before you boot it. Overtaking corners are after your fast right hand corners because you have the grip where they don't, and they break early.
