IndyCar driver Justin Wilson offers a turn-by-turn tour of the course for Sunday's race.
"Braking is really tough because it's so wide. And you want to really attack the corner and carry a lot of speed in. But you have the paint on the runway, so if you hit that paint, the car slips and slides. It's a really difficult corner, but it's really rewarding when you get it just right."
"Very difficult (in 2 and 3); not flat out. You've got to get the lift at just the right time."
"You want to carry good speed, there's a lot of lap time there but you've got the straightaway afterward so you've got to concentrate on the exit."
"Big passing zone, big breaking zone, it's very easy to lock up. The road isn't quite perfect. You can lock one wheel or another. You kind of slither into the corner, and we all know it's one of the big overtaking spots on the track."
"The next series of corners are one big sequence. How you get one affects the next one. You've got to get the line right in Turn 5."
"The grip level is weird (going through a parking lot). Then you pop back out onto the street before 7, and you've got a big crown in the road."
"There's a lot of time to be gained carrying the speed into 7. But also it's very easy to go off. You see a lot of guys lock up a wheel and go straight on into the wall there, and that's not going to help your day."
"I love Turn 8. It's one of those corners where every lap you think, 'I can carry more speed.' You aim to brush the wall on the inside, but you hope you're carrying enough speed that you don't hit it. … You've got to work the camber in the road."
"You've got to focus on the exit. … You've got a kink on the back straight, which is a challenge, especially when the tires are cold. The car bottoms out through that kink. It's flat out, but you can't sit back and relax."
"You're trying to brake as late as you can but also get a good exit. And there's a new curb (on the inside) that was new there last year. (The tire barrier on the outside) kind of sucks you in. I think there's a big magnet in there or something."
"Eleven and 12 are a lot of fun; virtually flat out. When the car's right, it's flat out through that kink. It's flat out, but you can't sit back and relax."
"It's a compromise of how much speed you carry through there versus what your line is for Turn 13. If you carry too much speed, you're on the wrong side of the road. You've got to turn in, and you lose everything you've just gained."
"Thirteen is such a long corner. In fact, it's classified as two (13 and 14). It goes on that long. It feels like in the middle you just sit waiting, waiting. (The grip) changes when you hit the runway."
"The car really starts to slide; really moving around all over the place."
