THOSE r some nice splits there shigspeed, if ur best T1 split was only .3xx, then u must be doing something wrong as the limit for T1 is a high .1xx, although i have never achieved that mark, my best was .211.
r u staying in gear 4 for the double left (using 290?) u should initially kill ur speed down to about 192ish as u hit the inside apex or just pass the first left and then sort of 3/4 throtle it at a nice 200ish speed, and u should really end up on the extreme right of the mid apex to allow ur self to maximise ur speed through the 2nd left, which, from the position i just mentioned , u brake dwon to 150ish, and just guide the car through the exiting corner nicely, dont worry if u slightly drift the car on exit either, u should start powering out at low 130's.
and the next left, skip over the right rumble strip (cutting it severly to stay as straight as possible, and then take the corner at 150, but do not cut the inside rumble strip, it effects ur exit speed, and thus, is not faster

take it at a high 140, and comprimise between having a high cornering speed yet achieving slower exiting speed due to not being able to power out early, and having a fast exit speed, yet a slow cornering speed. gt4 is all about making compromises. i hope that helps at all.
