Same here too! There just doesn't seem to be enough time to work the brakes. I'm just now starting to come to terms with when/how to use them instead of rolling through the turns. For me, the effect is so abrupt that it disrupts the car.

So far, only one of the settings that I've tried seem to be fit into my driving style. Drag Brake. I think that's because I don't have to actually 'use' it but I just 'rely' on it being there automatically when I'm off the gas. Roll into a turn knowing that drag brake is working and that's it.

As I become more comfortable getting around the track I am trying to experiment with other brake settings because I realize that this Drag Brake use probably isn't the best way to go in the long run. It's a challenge.
