Caster and Camber.

Yeah and people don't understand why. The reason is, the more you lay the steering axis back at the top (positive caster) the more you are picking the front end of the car up in turns. This is the same reason you get good returnability with a decent amount of caster. The front end of the car is pushing down on the suspension which in turn brings the spindles back to center.

Yup, exactly. What amount works best depends on the chassis, suspension design and set up. All I know is my car is pretty happy at +6.5°. Some of the new performance cars run as much as +7 to +8° in their factory specs, the Dodge SRT8 Challenger specs call for a +7.3 to +9.3° range for caster on the left and +8° to +10° on the left. Base model Mustang's are also in the +7° to +8° range.
