Yeah, that's what I said. In a perfect world the combination of your static camber, camber gain from the control arm travel, and camber gain from the caster angle would combine to match the lean angle of the car and keep the inside wheel flat on the ground to maximize traction.
@inertia 's question was about fuel mileage, and the way that the geometry works, if everything is set up perfect in a perfect world, you'd maintain the contact patch you'd have when everything is going straight and level. Realistically, the best you'll do is maintain the contact patch on the inside wheel, with the outside wheel patch getting smaller as the weight of the car is shifted. Regardless, you're not going to be increasing the contact patch overall, so, no lost mileage.
