Funny they aren't using the support series to go out first on friday and clean the dust off the track. that will be a fun practice to watch online.

It's like how the most useful groceries are at the back of the store... they're trying to get you out there early for F1 practice so you'll buy food and beer all day. Conversely the support events follow in the afternoon to try and get people to filter out slowly and not all line up for the buses at once.

Well, having flagged a Ferrari Challenge, there is not much change that any rubber would be laid down on the actual racing line.
