The first turn can be a solid foundation for a good run. I brake firmly about halfway between the first two brake markers, downshifting slowly rather than jamming the gears down. A little Scandinavian Flick while the car still has momentum and a goose in 2nd gear gets it rotated and ready to accelerate.
I hold third through the Slalom until the very end. The first right can be taken flat out; then immediately after each apex lift for just a fraction and start turning into the next curve before you complete the current one. The single cone at each curve marks the apex, and you want to brush the rumble strip just after this cone - but at that point, you should already be starting to steer into the next turn. If you're turning in at each cone you're too late. The last two are a little wonky and even though you'll be nudging the rev limiter, don't upshift to 4th until you apex the next-to-last cone (a right). Take the last one flat out in 4th and edge the grass on the right, but brake early for the exit 90 and get a hard late-apex in second gear. This gave me a T1 time in the 50.high" range IIRC.
