This setup will walk on the AI!!! I won all races in a row both A-Spec and B-Spec. This is for the AJ Allmendinger Fusion. I won the car, changed the oil right away before driving it and then rebuilt the engine as soon as I could. Change the oil again and you will have 892 hp! Here is the tuning setup I used for all races. Also be sure to TURN OFF ALL ASSISTS for both oval tracks only. All races use RACING SOFT TIRES!
Suspension:
Ride Height- F+15, R-15
Spring- F 18.4, R 18.5
Dampers(both ext and comp) F8 R8
anti-roll bars F6 R6
Camber F 0.5 R 0.5
toe angle F 0.0 R 0.2
Gear ratios by race, both A and B-spec:
Race 1: Indy, All assists OFF, Gear Ratio set at 224 mph.
Race 2: Grand Valley, Traction control 1, ABS 10, Skid recovery force on, Gear ratio at 193 mph
Race 3: High Speed Ring, Traction control 1, ABS 10 Skid recovery force ON,
Gear Ratio at 193 mph
Race 4: Laguna Seca, Traction Control 1, ABS 10, Skid Recovery Force ON,
Gear Ratio at 162 mph
Race 5: Daytona, All Assists OFF, Gear Ratio set at 224 mph. Stay low the entire race. Do not allow them to draft you!
Hope this helps. VERY frustrating race, but with these settings I won every race by at least 5 seconds.
