Apologies for the triple-post.
Ok, so best I can do for now is a 6:30 at about 1:55 per lap. Gives you 3rd place.
I really believe the Fit can do it, but it would require excellent driving skills. I think I have the right tune (sorta), just need to adjust my line.
So the tune is:
Height 85/85
Springs 3.8/6.7
Dampers all 3/3
A-R Bars 1/1
Camber .5/1
Toe -1/+1
Brakes 1/10
Trans at 160 top speed, 6th gear to 1.15
LSD 5/60/5
Since this is an FF car, understeer is a problem. So what's done here might make it counter-intuitive, but you turn by blasting the throttle. For most turns, you'll do some light braking into full gas to take the corner at high speed and not be overrun by understeer.
The most problematic corner is the last one as it easily makes you understeer. Getting the right line can shave off a lot of time. I don't have it quite right yet, but it's getting better.
Any suggestions appreciated!
