[s-cars] alignment Q

Larry - awesome feedback from Johnny Physicist.  Danka.

Wheels - no modification allowed, and all 4 must be touching track.

Dying to see it. And in terms of absolute gain in KE, it's based upon the difference of height, so if the track levels off at the bottom, then yes, having the weights as far back as practical (whilst maintaing front axle loading) would give you an incremental gain.

If the wheels are NOT a fixed size, diameter, etc, the most gain you can make is to make them as small a radius as possible, with whatever mass they have as concentrated towards the centers of the hubs as possible. And as noted, camber could intro scrub, and if you can try to get the car to two wheel, there would be less friction (and rotating inertia) because only 2 wheels would be required to rotate (so long as you can keep them from touching and trying to spin up). It's just like a turbo, smaller mass, smaller diameter, quicker spool.
