i got my T1 down to a reliable 20.4 by taking what i thought at the time was an unnatural braking strategy... braking early in a straight line, then powering through. I couldn't get below 20.6'ish by trail braking into the apex and motoring out.
was funny the first time i tried the early brake point. watch the ghost shoot past @ 162mph, then totally eat him before the next turn and keep pulling away through the S and onto the mid-straight.
I'm still totally beguiled by that long left in T2... as i'm only .2 behind the leaders @ T1, but almost a full second by T2. somehow i'm tossing > 1/2 a second in the trash in one corner.
edit:
and i just found out, apparently another tenth can be made up by staying in 4th (with the 270 gears at least).
got T1 down to 20.353; but my T2 is still disgustingly in the 40's... i've never seen 39. >:E
