Camber ?

[aaronng]

Negative camber also = handling, maximises contact during cornering where the cornering force on the tyre is attained at a negative camber level,but that being said, suspension travel and geommetry has to be taken into account as well..
Straight line stability plays secondary....

But more negative camber on the rear and zero camber on the front = more grip on the rear than the front when cornering hard = understeer.
