Tyre Camber (F1C)

Please be advised, this is not a professional explanation, only the one that
I posses as a amateur racer.

Tire Camber in racing applies to all forms, F1, NASCAR, etc.. Camber is the
outward or inward angle of the tire top to bottom. If the top of the tire is
angled in toward the car chasis, it is considered to have negative camber.
If it is angled outward, it's considered to have positive camber. The reason
one would want to adjust it is because when a car is being acted upon by
turning forces, i.e. weight and centrifugal force, it tries to push the
weight to the outside of the turn causing the tires to naturally want to
lean that way. One want's to keep as much tire in contact with the racing
surface to obtain traction. Usually, even, outer and inner tire temperatures
are a excellent indication that camber is set properly. Middle tire
temperatures deal mainly with air pressure. There are other settings of
course that contribute to the proper setting, such as sway or anti-roll
bars.

Hope this helps.

In terms of F1C, just set the camber fully negative.  Really, it
doesn't matter.

Might not matter from a lateral acceleration standpoint, but I find the
steering starts to feel a lot different as I go more negative in camber.
Turn in gets much sharper with more negative camber, to the point of being
objectionable if I go past about -4 deg. in front.

Sounds about right.  I set the car up so the springs/bars are fairly
tight (full front bar/springs and 1/3 to half of the front settings in
the rear) and the dampers make riding kerbs easy, then I crank in a
ton of camber so the car will turn easily.  I also run a tad less
wheel lock than the default settings to keep from unsettling the car
too easily.  The combination of pushiness and ridiculous camber makes
for a car that drives like a cadillac but still turns well.

F1C would be truly killer if tire temps seemed to have an effect on
the grip, but I haven't really found any solid correlation between my
cornering speeds (or laptimes) and how the tires and pavement are
interacting.  Plus tire wear isn't a factor at all.
