From the Track Fodder Foundation:
Bearing in mind, I am not quite up there with the leaders yet although I am now finally running 50.low T2 times. For those of you faster guys, feel free, make that, please do correct this as necessary. The point is to help those of us who are slower to get faster.
Inherently, because it is 4WD, my car has a bit of understeer when under power. I tuned that out as best I could but decided it was an effort in futility to think it would all go away and it would be better to find a line around the track that would allow for that. Additionally, I decided I could teach myself to get back on the gas later in the apex when the nose of the car was pointed more in the right direction. When you are in the current of the river, there is no sense in trying to swim to the shore until the river takes a bend. At that point, the current will naturally take you there. The same principles apply here only in reverse because we want to follow the current around the bend, not go to the shore.

Thus, we coast until the current turns our nose in the right direction, then we paddle.
I set my front end down, the springs fairly light, the shocks just above mid in the rear and lighter in the front mostly for coming up on the rumbles and leaving the rumbles smoothly. But the logic was also that it also helps to enhance the steering when getting off the gas from the weight shift when the car pitches forward.
I reduced the amount of camber in the front slightly to get a little more tread on the pavement and left the rear camber alone.
I buried the stabilizers at their lowest setting because the car seemed less jumpy there.
I set my brakes up and even front to rear so they would be predictable and feel immediate.
I set my gears low because I have always found that easier to manage wheel spin in the rain. I grew up driving in rain/snow/inclement weather and know the next gear up is where you go to get going. My dad used to say
Lug it a little Greg
youre spinning the wheels and you obviously aint going anywhere ya bonehead. Besides, I know my mom used to make me eat it but really do hate spinnage.
How low? Personal preference applies here but a good starting place I would use would be to look at the torque range of the car I am running and set it so that is where its taching at acceleration points on the track.
Knowing I would have to use a bit of rearsteer to offset the understeer, I lightened the downforce just a twitch so I could easily induce that effect (You guys running automatics I think need to do this). The counter thought here is the track is wet so the slightly lighter rear end needs to be managed at all times. You might not like it
unlike spinnage its an acquired taste.
Then, for grins, I put one click on the TCS mostly for the second corner but also to give a nod at the tight right (hairpin/ U turn?) on the second chicane like section.
With that "overintellectualized thought process"
I went to the track to play.
