In each race of this series, I pitted more times than the AI does. For some reason, they can handle a car on blue, green, yellow or red tires, with the same lap times. As everybody noted above, running your tires into the red is a bad idea. You'll lose more time on the track than you would have in the pit stop.
At Laguna Seca I ran these settings:
Springs: 17.4/17.5
Ride height: 45/45
Shock Bound: 5/6
Shock Rebound: 6/7
Camber 3.6/1.9
Toe: 0.5/-1.0
Brakes: 18/21
LSD: 10/23/20
Final Drive: 4.062
Auto Setting: Level 36
Down Force: 1.00/1.50
ASM = 0; TCS = 1
This was in the F094/h and after the oil went bad. So I was at 774hp.
The Pit Schedule worked like this:
I pitted on lap 7, 14, 21 and 27
F686/m pitted on lap 7, 14, 21 and 28
F094/s pitted on lap 9, 18 and 27
F688/s pitted on lap 8, 16 and 24
F687/s pitted on lap 7, 14, 21 and 28
F090/s pitted on lap 10, 20 and 30
I elected to pit on Lap 27 instead of 28 to give me one more lap one better tires.
Keys on the Track.
Take the corkscrew in a gear higher than you think. This is a trick that I use to lessen the chance of the car spinning down the hill. The same with the last hairpin. Buy going through the corner in a gear higher, you lessen the chance of wheel spin (which eats up your tires).
Additional Notes:
The AI is really spot on in this race. You need to brake earlier than you think, and take some corners faster than you realize. The Left hander approaching the Corkscrew can me taken wide open. Just know your turn-in point.
Good luck, and keep us posted.
