With Viktor's setup I did in TT 1:23.3xx, which is shame of me, I made alot of mistakes, on other laps i was always getting "corner cutting". I feel like I can hit 1:21.5xx, just need to set ideal lap without mistakes.
Here's my own setup from career mode (Red Bull Racing, 1st season with this team)
Car
RB6 (Red Bull Racing Renault)
Aerodynamics
Front Wing Angle: 9
Rear Wing Angle: 3
Braking
Balance: F 48% - R 52%
Pressure: High
Brake Size: Standard (career, can't choose other)
Balance
Ballast Distribution: F 60% - R 40%
Front Anti-roll Bar: 3
Rear Anti-roll Bar: 7
Suspension
Front Ride Height: 2
Rear Ride Height: 3
Front Spring Stiffness: 8
Rear Spring Stiffness: 5
Gearbox
Gear 1: 140 kph / 87 mph
Gear 2: 159 kph / 99 mph
Gear 3: 191 kph / 119 mph
Gear 4: 219 kph / 136 mph
Gear 5: 256 kph / 159 mph
Gear 6: 295 kph / 184 mph
Gear 7: 315 kph / 196 mph
Engine
Throttle map: Standard (haven't get R&D yet)
Fuel: 4 (@ fastest lap there was fuel for around 2 laps)
Alignment
Camber front: -0.80
Camber rear: -3.20
Toe front: 0.15
Toe rear: 0.41
Time: 1:27.489, 1st Free Practice, so @ Qualifying time will be lower (I hope a grip level is improving through the weekend, but it's CM game...). For Race I'll have a bit different setup, because fueled car is a crap (I'm doing 50% races).
Don't know how about you, but I personally liked high downforce on this track. Making me alot faster on corners.
@Edit I've forgotten about one thing... No aids in both modes (TT and Career)
