I'm going to write a little guide for this event.
I cross the line at 260, in some cases 261 km/h, I hold the inner side for the next corner, hit up to 290291 km/h on the straight, turn in on the inside, exit on the outside, hitting up to about 291293 km/h before braking hard while going on the outside for the 2nd corner beeing very close to the barrier, the closer you get to the barrier the faster your T1 time will be, try to turn in after braking to maximise your exit speed (I take this corner in 4th gear). Exit speed from corner 2 should be aboutover 200 km/h. I move to the left, brake just as the road widens after the bridge, brake hard while downshifting to 3rd, then I start turning in at the 3/4 of the kerb on the right and downshift to 2nd for easier turn in. After I've cleared first of the S bend I then move to the left, apply about 2% of brakes and downshift to 2nd and start aiming for the apex near the kerb on the left. When I hit the apex I then start accelerating and exit the corner near the right side of the tunnel wallI take the S curve just so I can get on the throttle as early as possible, even if it meant not hitting the apex and taking the middle route, speed is key - the earlier you can get on the throttle the faster your time will be, for the exit just do the same. From there on I cut the concrete after T2 (this is track as stated) and before the final corner I brake just a little bit so I can downshift to 4th, I enter the corner while trying to not go under 200207 km/h. I hold the outside line in the last corner in order to maximise my speed and if I did everything right my speed at the line should be 260 or 261 km/h. I shift at the redline.
I hope this helps.
