I just did my last run as I'll be away this weekend. I got a T1 of 14.2, but was .2 off my best T2, I still managed to cut .25 off my time, If I drop another .5 I'll be happy. Although then I'll be painfully close to the next second barrier that I probably won't get...
For the T1-T2 Run, just studied my lap and is as follows.
Chicane after T1 I take in third and power down in the middle of the L/R, then 4th gear change for the flat (Depending how wide and stable you are) R/L combo.
The next stupid R/L is a pain, because of the bump, sometimes I use the bump to get a slight drift, but normally I brake not from the left but the right of the track just before the RHS blue/white strip, down to second, get as close to LHS wall as possible on the exit which is flat.
I keep it in second for the hairpin, power down about half way to tuck the nose in so you're wide enough to take the next corner flat in 3rd.
(Fastest T2: 42.6, Average 42.8)
Kink can be taken flat, but I let off slightly on this lap just before the LHS apex. Hit the limiter (230 gears), and brake slightly early at 50 sign, to get the power down early (3rd gear in this corner), so you're wide enough for a good line in the next left.
Next Left taken in 2nd, if you got good exit you should get a quick change into 4th before the final L/R chicane, which are taken in third. The final turn I take in 3rd and my lowest speed is 62mph, change to 4th on the way out.
