Here are some pictures of my rear tires. Surprisingly, I took them when I got home, driving some 40kms from the track to my home. Apparently when the tires have cooled down they resist further wear much better.

Looks normal for an S02 that's been understeering. At least there is no chunking.

 

How can you tell if it is understeering (or oversteering)...even just a little?

Looking at that pic, how can you tell it's understeer?

 

Because that's what my S02s looked like when I started understeering a lot. If you were oversteering enough to do that you would probably be in the wall already, so it's a pretty safe bet its from understeering.

 

Is that caused by certain alignment types?

 

Your guess is spot on; I experienced hardly any oversteer at all.

I have had a full re-alignment done in december and drove around 6000km since. I don

 

No, it's caused by going through the corner faster than the tires can stay in contact with the road.

 

I see, is that being consistent with going fast into slow turns? I think that was mentioned earlier...

 

Yes, exactly. "Too hot"

 

This is correct, but...the alignment can dictate how fast a car can go through a particular corner before the tires break adhesion
