Thanks!

I use BB 2, it makes the braking little hard, but car rotates better.
Few points that made my laps faster, for T1 if you got the entry right, you can go on throttle sooner and not spin tyres. There is a dip at the track that pushes the car down.
For T4, brake early, but just a little, trailbrake to apex and full power from there. Car will stay on track if you dont lift. (Well i have hit that barrier more than many times

)
For down hill Ss turn in earlyer than you think, in both corners. Try as little steering input as possible, turn too much and car slows down.
You should get good line to uphill left keep on the curb untill it ends and start turn right. I lift slight to start slowing down for the last hairpin.
Hairpin is tricky, for me the key is to keep enough speed thru whole hairpin. Braking will easily upset the rear here, so be carefull and slow down early enough. So brake early but not too much.
