I may not be the best at this section either but this is what I do.
I start my turn in at the end of the rumble strips on the left at the start of the ring. I lightly touch the brakes and downshift to 4th while keeping my speed around 105-110 mph. I do what I can to stay on the white line until the first set of billboards on the right. Around that area, there is a hump that will likely make the car push to the outside. By that point, I go to 5th and I let the car go up the middle to start preparing for the exit.
Around the first support pillar on the right (note that I use bumper cam view), I ease off the throttle a little, downshift back to 4th, aim for the white line and nail the throttle again. When I have done it right, I'm at the edge of the limiter on 4th and it lets the car turn easier (for me, anyways).
Actually, my exit is somewhat like Hunk's but in my case, I'm going a bit faster and I'm a bit higher so that I can cut down to the apex better.
