Technical question
Can someone explain a couple things that have come up in the F1 broadcasts this weekend?
The first was during practice when Peter Windsor said that Kimi is taking a different line from others down the back straight of Monza. He's coming off a corner and rather than "going across the track lazily to set up for the next turn", he is "staying straight, track right, to get all the lateral load off the engine and then coming across the track at the last possible moment (track left) to set up for the next turn". This is getting Kimi an extra 100 RPM going down this straight. Please explain.
The second quesiton has to do with a shot of the BMW rear wing vs. the McLaren wing. There is hardly any downforce on the rear wings for this track at Monza and BMW has placed a "rake" on the back edge of the wing to "control the vortex". I've seen a similar rake on the rear roof of a Mitsubishi Evo (stock). What does this do exactly? The McLaren's do not have this. What is the benefit to not having this rake?

The sawtooth wicker is merely just that, a wicker. Its known that a sawtooth wicker produces ~7% less drag than that of a solid or flat wicker, 66% of the height of the sawtooth iteration. Just a little more efficient is all.
