Istanbul Park is a challenging track from a set-up point of view because of the variation in corner speeds and grip levels.
There are the very fast changes in direction at the start of the lap, there’s a long straight and then some slower stuff at the end of the lap, which makes set-up a compromise.
The asphalt also changes a lot around the lap: it feels very slippery in the last sector and then you have a lot of grip in the first sector.
People talk a lot about the long turn eight. For me, it’s just bumpy and a neck-killer; it’s not a place where going haywire gives you a lot of lap-time because that’s never the case in fast corners.
