huh. I don't remember what mine say, but I thought they read from like -10 to +10...........can somebody else back me up or prove me wrong?

why would you want negative camber in the first place?

You can't set negative camber in GT, but you can get a negative toe setting.
A positive camber setting affects how forces are acting on the car, pushing it downward, and how the car's suspension will tilt the loaded tire when cornering.
Since during any moment, the loaded wheel is either completely unsprung (almost never, slightly >0.0 degree) to the hardest possible loading (a heavy car entering a corner too fast), there's no need for negative camber ratings, unless a tremendous force is acting on the underside of the car. Since we're not dealing with an airplane, negative camber wouldn't be of much use in an automobile...

Nope but make sure you dont have too much positive camber because it will affect the accleration and turning and even the braking of the car meaning too much camber you will lose power and grip.

you can set negative camber. you're right, the gauge does read from 0 to 10 degrees, but it's degrees of negative camber. god know why it's setup like that, but a 5 degree setting is g degrees of negative camber.
you can set neg camber
no no no no no.
a positive camber setting tilts the wheel outward at the top. that's all it does. typically it'l reduce cornering grip to have a positive camber setting.
what are you talking about aircraft and unsprung weights for? camber affects neither of these.
negative camber on the front of a car will improve cornering grip at the cost of braking grip as the wheel will sit flatter while being leant on, but in a straight line the contact patch is reduced slightly. a small amount of neg camber at the front is usually good thing.
negative camber on the rear wheels will induce understeer and allow the tyres to break traction under power. generally neither is desirable in a race setup.

Since the weight of the car pushes on the suspension, which in turn pushes on the tire, the contact patch is going to be slightly angled outward. When the car is moving in a direction, the tire's going to need positive camber to counteract the forces the movement of the suspension create.
Camber: A little is good, but too much causes too great an angle between the tire and the road surface during cornering, and you lose grip.
In GT2, you'll probably do best with an angle of 0.5 - 1.8 in the front, to 1.0 - 2.5 in the back. I've never need more than that, because of the resultant loss of grip with anything greater than that.
Too much camber:
You might swiftly get around the first part of the turn, but you'll lose the rear end or understeer coming out of the corner because the tires have less contact patch to stick with the road.
Too little camber:
Works better in my opinion, with light, high powered, non-4WD cars like the Cerbera LM, Speed 12, Venturi 600LM, and a few others. But you may find a bit of initial understeer to prevent the rear from slipping away from you on exit.
Again, just a few observations. I'm going by the physics model of GT, not necessarily real-life.
And in the real-world of setting up road cars on the alignment rack at the Lexus service ceter I work at, we never set negative camber on the cars. Only positive settings, or the tires become smoked meats in no time, thank you very much.

A tyre does not need positive vamber to couteract the forces (leaning car) of cornering. It needs NEGATIVE camber. in GT2 it is misrepresented as a positive number, but the slider is truly affecting negative camber.
For and car in GT2 a small amount of neggo camber can improve grip. and by small I'm talking 0.3-0.5, any more and you lose grip as you said pupik. as soon as you've got slightly hard suspension a setting of 0 is optimal. GT2 doesn't model tyre deformation and as such it it unnecesary to lean the tyre in by any more than the car leans out. on a stifly sprung car it's unlikely to lean at all.
an a general medium power vehicle set 0 degrees at the rear and around 1 degree at the front. and neg camber on the rear is a bad thing. a little on the front is good if you've got stock shocks.
