Good place to start i supose, btw atm im in the middle of the FGT championship B-spec and i was wondering whether to pit in or not, the opponents haven't yet but i reckon that they will?
They only pitted on 2 of the races when I did it, the strategy I used was racing softs, pit half way through each race for enough fuel to finish. That won all of the races except Cote d' Azur.
