Sorry STuart i clicked on the wrong icon and exited the game , by the time i got back in you had gone., the problem is the track surface , with 1 or 2 drivers it takes ages to rubber in and give grip , you need to do 100+ laps , when the grip is there these cars are as fast as the F3s and become more managable . Try them offline , the AI cars rubber in the track for you fairly quickly and allow you to develop your setup
