If I may be further bold and make a few suggestions on how I drive this track.
First corner right hander 4th gear is safe 3rd gear can be a little quicker but more risky. Keep it tight to the apex as possible without touching it. If you do you will have to be more patient and wait for the car to settle before you can get the throttle on. Avoid the kerb on exit as much as possible, if not completely.
Next right hander change down to 3rd gear in quick succession you can go down to 2nd gear watch out for back end lock up and avoid the kerb on exit especially if you're in second.
Flat out including the slight left. Hard on the brakes down to 3rd gear and as you were going around the left short shift to 4th gear with the smallest of lift, if at all. Or keep it in third with a bigger lift. Keep the car far left as possible on to the right hander make sure you get that apex or be prepared the lift off as you will run wide on exit. A lot of time can be made on that section of the track.
The next right hander down to 4th next right hand down 3rd gear keeping it tight to the apex and once you know you can get the power on, floor it.
The final right onto the start and finish straight. 2nd gear. Avoid the kerb on entry, on apex, on exit unless you've got the car relatively straight. All the kerbs are dodgy under acceleration trial and error.
I hope that makes some kind of sense and helps a little.
PS: As in most cars do not hit the rev limiter it slows you down. It's better to be early than late. With a final drive of 5.00:1. You will hit the limiter, if using DRS and in the draught of another this final drive may cause you problems on the straight after the first right. If you are that close behind another you probably wouldn't need the DRS it's probably worth saving for the following straight but make sure you turning off for the slight left.
This is what I found out so far so things may change as I'm still testing.
