I can't record a video, so I thought a brake marker and minimum apex speed guide might benefit some.
Sector 1: there's a 100 meter sign on the left before the curb, before that there's a white sign on the right. Brake at the 3rd fence post on the right. This should put you on the inside line, try to keep 65 or 66 mph. Once you get half way through the corner, you can full throttle without a spin.
Turn 2 is important as well. You can gain a bit of time by hooking your left tires into the left rumble and coming out just before it straightens.
Sector 2 - I haven't found a stationary braking point other than just a hair after the Sector 2 split. Try not to dip below 44-45 mph into the corner. As soon as you hit the dip, go half throttle and work your way to full just before you're straight.
The kink in sector 2 is really hit or miss and your sector 3 depends partially on a good run. Just before the kink, you'll see a rectangular shadow, hard on the brakes right before it ends, let off just before the turn, and try to run over the rumbles. When you hit the apex, apply a small amount of throttle to keep the rear from stepping out and full throttle when you hit the outside apex. Key speeds for this turn is 84/85 mph.
Sector 3 is all up to you
