That tough downhill off camber left... brake hard and early, leave the throttle off until the apex and then let the car accelerate without requiring the diff to work, it pays off huge in time even before you set the car up for the next right hander.
I set up for the double apex rights by letting the car bog down in 3rd, then shift to 2nd when the speed drops to 57 mph, then careful to avoid upsetting the rear as I crest that pointier left hand apex without lifting, let the car just barely touch the outside right curb, then late apex the left hander, again so the car just 'barely' touches the curb on the left (any significant contact will send the car into a bad oversteer) and TRUST that it will stick without lifting when I feel that little bit of curb. From there it's a late apex and REALLY smooth throttle control off and on until I perfectly arc the last right hander to the apex just after the entry path.
A lot of the speed is just keeping the car from oversteering during that last 10-20% of throttle... any slip sideways kills the time.
In general, that track and these cars really reward the patient approach to be earlier on the brakes, and then a smooth early power-on... the earlier and least dramatic, the better.
The first turn, I brake just after the heads-up flashes, I brake hard to 59 mph, turn in late as possible and keep it in 3rd to take off smoothly. It sounds and feels slower, but the running time indicator shows how much time you can grab by keeping it undramatic there.
