^So it has the same static footprint of a normal tyre, at a higher static camber angle...? This isn't going to change the effective footprint of the inner/outer tyres as the car goes through a corner, so what's the point? Wank?
Looking at it, the only way this could be marginally more effective would be if the car had no suspension at all, and thus these would offer a slightly wider track width while maintaining a full contact patch.
