What colour is fastest? Because it isn't white.
Can't get anywhere near a fast time in T1, no idea how you guys get into the 24s

I swear the grass on the right after the first corner gets closer each lap.
At the risk of being passed, here's my turn 1 writeup. The tunnel turn is much less consistent for me, and I'm convinced that's where I'm losing the majority of my T1 time, my turn 1/2 is pretty solid.
Coming down the front straight, make sure you do a blip into 5th, even if it's just for a moment. The downshift into 4th helps with weight transfer and getting the car pointed.
I've tried kicking the car up onto the rumbles on the right hand side of the track, but that's not necessary to pull this off, and might actually be slower that just being on the very outside of the tarmac.
Just after those rumbles start, downshift into 4th while braking VERY lightly, and aim for the first apex. As you come to the apex, brake more, and downshift to 3rd, and let the car carry all the way out to the right rumbles. All of that should be one smooth, relatively fluid motion, the car should make it's way out there smoothly and on it's own, don't force it.
The shift into 3rd BEFORE hitting the rumble is essential, in my mind. It causes the car to become unsettled when it hits that rumble, and if you aim for the second apex with some more aggressive braking right then and there, it will rotate the car for you and take some of the needed braking out of the equation.
Try your best to get the car to that second apex rumble, but the main thing is to be far enough over that your momentum as you mash it back to full throttle doesn't carry you out into the grass on the right.
You'll feel it when you get it right, but the main thing is to be smooth, brake lightly, and use the gears to help the car rotate.
