Looks like it's going to be a rain affected weekend, there could be as much as 2mm...

That is the average rainfall total, the rain could just as well miss the circuit and tomorrow could merely be overcast, it won't be heavy rain. The rest of the weekend appears to not have much rain, maybe even some sun to warm up the track.

Tripod is placed right at the last chicane...

How deep was the rut in Sochi at the braking zone for turn 16?

That little rut was only ~3mm deep and was the difference between locking up and nailing the corner.

Then you have to wonder, were Mercedes BS'ing when they told their drivers to stay off the kerbs because they didn't want to lap the field twice? Or does their car have a fragility that aggressive kerb hopping exacerbates?
If the RB16 is better at late braking and change of direction and straightening out and riding the curbs
If the RB16 was better in those area's, wouldn't it have won more races this season?
What?

Total forecast is 11mm for the day with 60%-90% chance of rain every hour. I wouldn’t bet on any dry running tomorrow. With temperatures of 10°C the circuit isn’t going to dry quickly either. Saturday and Sunday looking dry but overcast, isolated showers are still possible.

The whole weekend is very cold for an F1 race.

Looks like DAS will play a huge role this weekend. Slam dunk front row for the Mercs.

How? If the main benefit of DAS is to add toe to keep temperature in the tires, why not just run fixed toe? In these circumstances it makes no difference because you won't want to lower toe to cool the tires on the straights, ambient temp does that for you. You want to scrub the front tires on the straights to keep heat in them. DAS lets you change the wake profile of the tire, which is nice, but probably not worth a ton of time.

In fact, if DAS is why Mercedes can't slam over kerbs, it may hurt them here and in Imola because both tracks require you to slam over kerbs to be fast in the chicanes.

Because running DAS levels of toe permanently would make the car an absolute dog to drive. And it would cause excessive tyre wear if ran for a whole race. I don't think tyre wake was ever a consideration with DAS as it was never meant to be for any great length of time or under full load cornering.

The tire wear at the rear is much higher than the front, so you run toe to match front to rear wear, otherwise it will change the balance of the car mid stint as the fronts will lose grip long after the rears. Most teams will run a slightly oversteer setup, so not balancing wear rates will hurt your pace.

Really? That'll be very mild oversteer in slow corners that is aero balanced to give very mild understeer in high speed corners, presumably. No one runs high speed oversteer intentionally, that's for sure.
If you are more fortunate than others, build a larger table not a taller fence.

It helps around here, I promise you, you need good turn in especially in sector 1, the interesting part of this circuit is the positive cambers that help grip on exit. So if you have really good turn in, you can set up the car very well for corner exit and then just lay the power down. The high speed corners have camber helping you on exit so you can live with a bit of high speed oversteer. It will make the Shumi S more tricky in the rain but nothing the drivers can't handle with all the aero these cars produce at 220+ kph.

Maybe I'm missing something, but can't they run DAS to temporarily increase toe on straights to generate heat (or rather slow down heat loss), instead of temporarily reduce toe to reduce scrub?

Anyone know how much range they have on the toe adjustment? 2deg?

--- man that's 1mm too many I predict multiple safety cars.
