Assume a nonsteering wheel : according to the figure on :
http://www.racesimcentral.net/
the result of the inclination, but in LFS for example you can set all 5
shown parameters independently. Could anybody shed some light on this :)

He's talking about how camber CHANGES during wheel movement.
The example given only considered wishbone suspension and is correct to a
point .
Trailing link suspension doesn't change camber ( but MAY change caster if
the upper and lower links are different lengths )
I don't have LFS, but I assume what you are allowed to enter is the STATIC
value for these 5 parameters.
Any decent race suspension will enable you to adjust everything in a static
situation.
How it behaves under compression and extension may not be modelled on the
game.
If it was, then they would have to get smart about the type of suspension
and control inks.
Leave it to others to confirm LFS.
Yes, but that figure is for a "steering" wheel and 3 of those 5 factors
(inclination, scrub radius and castor angle) only apply to those (as they do
in LFS). That's steering geometry and almost independant of suspension
geometry.
These 3 factors can have an effect on camber as the wheels are steered. See
certain Formula Vee's and, most famously, the 2CV for a graphic example
(<--- now that car, in rallycross gise, would be a hoot in LFS <g>)
Non steering wheels only have camber and toe. Camber can change over travel
as a function of suspension geometrie, following the so called camber curve.
If you really want to know about this stuff, read "Tune to Win" by Carroll
Smith, take two aspirin and don't call me in the morning. <vbg>

Bump steer is an effect due to track and radius rods also being attached to
the wheel hub/uprights. As I understand it, it is adjusted out as much as
possible by moving the attachment points of same up/down slightly by
shimming, not by changing inclination/scrubradius/caster. Nor, again: if I
understand correctly, does the adjustment affect static camber/toe.
I know, I just don't see how it pertains to the question. Which, I'll admit,
only understood afterwards as well.
Jeez... no respect. ;-)
