I have a g25 and i use manual clutch (for the start) and left foot braking. I played a long time with the right foot at GTR 2 and after at Race 07. But one day, during a little "hotlap challenge" with mister Attila Domjan on Zandvoort ( if i remember well, it was on Nogrip...), i have discovered after analysis of a replay of the sir, which he braked down and throttled at the same time to spend certain bends. Of the blow I said to myself that the only means to become faster, it was to learn this technique. It was hard at the beginning to find a good sensibility of the left foot, but now I can more drive otherwise, especially for the GT, that helps enormously to stabilize the car during the brakings and huge throttling.
