RB are running less down force, so they're 6 or 7 kmh up on the straights. Its mainly a fairly fast circuit, and they're relying on Max's talent to manage the fast corners with the lower down force.
That should also make it easier on the tyres. If he can get away clean and keep clear for the first lap I think he may do it, but with weather and track condition variables thrown in id hesitate to forecast this one myself. Any of the top 4 qualifier are in with a chance tomorrow, and theyre all race winners so far this year. It could be spicy.
Personally, I think RB are playing Russian Roulette with a low downforce set-up given the forecast - the old "win or crash" thing. If it stays dry, they *may* pull it off, and everyone will be saying they're genius. If it's wet, the car just simply won't have the grip, and Max could end up decorating the scenery in quite a big way.
I guess, being so far back in the championship they've nothing to lose by trying something a bit crazy.
