More camber needed? (autoX)
I ran the autoX this weekend at Englishtown and did pretty well. Iwas right in there timewise with the C5 and C6 cars. Only the race tire guys with setup carswere beating my times by a few seconds. Anyway look at the tire pictures. It looks like I am hard on the center to outside edge of the tire. All 4 tires are worn about the same. The car is pretty neutral and not much body lean. Is more camber going to help out on the contact patch.

I don't aurocross much anymore, but when I moved up to 17 and 18" wheels and wide tires, the outsides were wearing out quickly. I tossed in a negative degree, front and back, and now I get even tire wear. But this is on the street with some, ahem, enthusiastic cornering.

PS. -1 degree doesn't sound like much, but everyone points out that my tires are tilted inward on top on both the Vette and the Porsche. I guess it's visibly obvious.

About negative 1.5 camber is a good starting point for autoX and drive on the street. More than that is possible but you will start to get limited by the a-arm studs and the number of shims you can get in there.
I can't see the pictures here at work but if you were running street tires at the event, did you have the pressure up around 40psi? This high pressure is needed to help a street tire from rolling over.

How much camber do you have now? It does not look that bad to me, you will typically always wear the outsides of the front tires more than the insides, but from those pictures (and I'm assuming this is your left front tire) it is not rolling over to the point that the wear is crossing the thin molding line on the left side of the last pic.
If you want to maximize the life of the tires and even out the wear, take the tires and flip them on the rims, then swap them left to right so that the outsides of your left tires become the insides of your rights, and it'll even out the wear.
