Generally the rule of thumb is that more toe-in increases understeer and more toe-out increases oversteer. However, with modern cars, especially race cars with independent front and rear suspensions, there is another effect on handling.
A negative camber setting can provide increased handling during heavy cornering. However, it generally reduces the contact surface between the tires and the road surface during straight ahead driving. Positive camber may be ideal for off-road vehicles such as large agricultural tractors.8 jul 2013
