This is a little dirty trick I've been using to go through fast exits, especially at Daytona oval and this one downhill at Bathurst. 

The sequence is: start unwinding the steering as soon as you push the gas, and since then keep looking at a point down the road where you want to be next. 

For the turn below, the target is somewhere near the red banner, past the red wall.

That is also a point to stop unwindig, so this helps focus on the gradual, smooth steering and not worry with the wall and pavement moving 200mph backwards. This will make you confident you're not spinning loose mid turn.

And of course you must use all track width...

Turn in a little before the Apex (for powerful cars):

And delay a bit the return to the road. Wait the car be stable first. Then let it flow.
