Alignment settings
I am quite amazed how pissed S2KVT's wheels were:
Front Left: Camber -50min, Toe -4.6mm Strut Angle 16deg28min Right: -7min, -0.3mm 10deg35min.
Rear Left: Camber -1deg49 (about right) Toe 4mm Right -1deg11min, Toe 2.1mm.
Must've been in a permanent left turn. I thought it was chasing the camber badly! It was getting a bit oversteery in right turns too.
Feels a bit floaty on the new rears, like last time, until they settle down, but does drive straighter and the steering's lighter. So no real difference beyond new tyres, then.
We'll have to see what effect (if any) it has on the wet road breakaway
Since this is probably the result of 18,000 miles on third-world roads and some cars leave Togichi pissed, I would recommend that everyone get theirs checked, if they haven't.

Alignment is a general term for the geometry settings.
It is normally just the tracking (toe-in) that is checked, as with most cars the other aspects of geometry are not adjustable out of the factory. (Unless you use a body aligner to bend it!) That basically affects steering feel/weight, straight line stability and stability under braking. At the rear, it can have additional cornering effects too.
Our cars are fully adjustable, so there is a lot more to be checked:
Things like caster/camber/steering pivot angle have varied & incredibly complex effects of the handling characteristics.
Suspension geometry as a term also includes the length of the upper & lower wishbones, the height of the roll centres of the car, steering effects of extra links etc.
In the old days, they tried to keep the tyre upright for maximum grip, as the car rolled through a corner. Nowadays, the engineers make it do all sorts of strange things under different conditions, to fine-tune the handling.
It is an incredibly complex area, but I hope the above helps a bit.
