Here's my strategy. Fast cars wear out tyres, upgrade tyres, steering brakes and team early. Leave the speed for your driver. Then upgrade acceleration to get out of trouble fast. I go defensive for first lap so others crash and pit and I get a clear run in extreme setting.
I want this gane to be great but the AI does suck. Is it stock car racing or F1? No matter how much I develop the car and driver I just get totalled every race towards the end. :(
