Camber settings maximize grip whilst cornering due to body roll..
Most of the time front camber is used along with more castor ( not changeable unfortunately in GT5, But the angle of the suspension in relation to the front and rear of the car.)
Drifters will oftern use posive castor if changeable with negative front camber to get a bit more steering lock on the vehicle, and more steering lock = bigger angles.
now onto rear...
Now cambered vehicles just look completely gangster anyway...
sorry back to rear camber...
As we know increasing camber increases grip in the corners as stated above, when not cornering, there is less tyre tread touching the road....less tyre touching the road = less grip/traction = easier to spin the back wheels up, useful on less powerful cars which may struggle to spin the wheels. A number of factors when choosing camber can be power of the vehicle (does the car struggle to spin the wheels?), tyre sizes, are you running massive tyres? as before more rubber = more grip solution wind on some camber..
other bonus-uses can include stability before during and on exit of the drift, and increased entry response...
However.. Camber only bonuses up until a certain point of grip. I.e If i wind on -3 degrees it will only aid grip until a certain point, then it doesn't grip anymore and in fact provides less grip duue to less tyre toucing..
its more trial and error to find out what suits..But combine camber and raised tyre pressures (again cant do on GT5) for less grip.
Here are the facts..
another reason for camber is..
Lowness:- if the car is too low and wheels too big camber can be used to fit the wheels in the arches if the arches are standard.(common in the Euro/Dub scene).
