Bon jour.
About Oz, I'm using 83 for wings, and not very much camber (-1.60). Ride is 85 and springs 35/25. I always tend to put rears softer to get a little more traction. Brake bias is about 80
About the track, chicanes are decisive. The first one, after main straight, I brake very late and cut a little on the left, not much because grass slows you down (don't cut on the right). The first right turn must be taken very fast, which means you cannot brake very late nor hard. When you get to the first split time you must be a low 27 s (my record is 26.850). The next chicane, the slowest, is the most important for me. You need to do it very smooth and cutting very little on the right (or you get a red) and trying to step not much on the left curb, or you won't get enough speed to do the fast sector before the fast chicane (some kers now). There, I don't step on the left curb, as Jay was saying, but probably it doesn't penalise your time if you do it (my 2nd partial is 49.3). The most important is to go out very fast and push a little kers on the straight. After the straight, i brake well after the last orange post, but trying to keep high speed to do the righty, but without going wide (like Vettel). The penultimate, a lefthander, has ruined me a lot of good laps. You need to brake very hard there, just before the 50m post.
Did you understand a single word of my English?
EDIT: I've passed the 2nd sector once in 49.1, so 1.19 is theoretically possible for me
PS. Oz is a word that I've learnt here (though I've been in Sydney, back in 1998). So, besides my virtual driving skills, I'm improving my English thanks to Codemasters and you all
