Try Pekka's setup. I was running Bart's with min/max ride height, but only .05/.020 toe; so Pekka's should be really quite safe; I found the car quite manageable (it's still very easy to go make sandcastles if you brake late, natch). Also stay off most outside kerbs, especially if running higher toe/LSD Accel numbers (like Bart's/Pekka's). Brake straight; downshift later rather than slammimg it down early if you need more stability.
I didn't get any practice outside of pre-race warmups, so I didn't get to do much refinement, nor did I get to check TT replays (they'd be very educational this week, and likely will be next week, also), so my advice probably isn't worth much. I was staying in 3rd for Degner 1, braking very early for Degner 2 and taking it in 2nd (very late apex, I guess). I was upshifting slightly early for the kink before the hairpin for a little more stability into the braking zone. Still had oodles of time to gain in Spoon and turn 1-2, more bravery for 130R, and there's always more in the esses (especially with setups requiring more finesse).
There was really cool seasonal ages back, 550pp road car 4 lap race w/SS at Deep Forest; it was good to run a whole bunch of cars 480-550 stock on SHs. The F40 wasn't even in the hunt for Ye Olde Best Deathtrap. (*cough* BTR *cough*)
