A lot depends on the car. In a lower-powered car I brake lightly first just as I pass over the hill and gradually brake harder so as not to lock up the brakes and smash into the wall. As I approach the corkscrew, I let off the brake a little and steer to just touch the left-hand edge. Then I coast down and slowly get back on the accelerator and aim to just touch the right rumble strip at the bottom. Hitting the gas too hard will almost definately cause the back to come loose. In a high-powered car, I brake earlier, just before going over the hill. It is even more important to keep the brakes locked up in a high-powered car. The rest is the same: just graze the left rumble strip and then accelerate slowly, just grazing the right rumble strip. For me, the most important things are keeping the brakes from locking up by braking early and lightly, and easing out of the turn by slowly getting on the accelorator. I used the right analog stick for gas/brake so people who use the buttons may have more difficulty with this. I would say that this is my favorite turn in the game.
