From memory:
You should be crossing the line at 128/129/130mph. Move across to the right but don't go near the edge. Begin to turn in gently, you're aiming to place the car alongside the lefthand kerbing, and you've got to get the car straight to do it as early as possible. You can either straighten and lift, or be more aggressive by tapping the brake while you've got the throttle pinned.
As soon as you get close, you need to brake hard past the first apex, and come down to 3rd and 70mph. As you get towards 70mph, you have to be turning right, but ideally, you won't be getting your tyres over the kerbs on the right at all.
Perfect method is to get the car yawing clockwise, translating right, but not putting the front right wheel over the kerb. As soon as you think you can, nail the throttle and if you've got it right, third will be enough to push the car forward in drift, the car will go over the crest and start to acclerate. You'll need to correct, but ideally not much so that the car drifts left towards the oet-hand exit kerbing. You should be parallel to that kerb on a perfect run and acclerating.
Once it's straight and not drifting anymore, sweep to the right. You'll be approaching the second S quite quick if you've got it right, and you'll have to choose between unbalancing the car on the entry and trying to drift the left and flick it right under 'some' brakes as you climb hard.... or.... what I do is lift off and brake down to 105ish on a smooth entry arc,
not clipping the lefthand kerb, then letting off the brake and
not clipping the right hand kerb while applying part throttle to keep the car above 75.
This is where it usually goes horribly wrong for me, and I spear off left or clip the kerb and spin into the marshals box on the right.
If you've nailed it, you'll feel the car unbalance itself over the crest near the second apex and drfit left towards the lefthand exit kerbing. The key is not too apply too much throttle while you're still drifting, or at least, be aware that the car will try to spin clockwise if you do get heavy footed.
EDIT Oops, too late.
