Tire wear pattern - suggestions on alignment? (warning: big pics)
Front is -1.9 camber, slight toe out, rear camber is maxed out at something like -1.4 with roughly 1/16 toe in. I don't have the specs on me.
OEM tires, MPSC2.
Rear sway is set to full stiff, front sway was set to middle but I just changed it to full soft.
Car is mostly auto-x'd with some local street driving.
I don't have a temp meter.
Suggestions on sway bar and alignment? The car feels balanced and based off tire wear do you think I can get away with more front camber?
Sometimes it plows a little, would stickier tires in stock size help or should I move to 255?

Tire pressures are 29/31. Should I go lower in the front? My concern is the #3 rib from the inside is shaved down on the outside edge and the outer edge of the tire is starting to wear.
I'm not noticing any unusual camber wear on the inside edge so I'm wondering how much more front camber I can get on stock parts before wearing the inside edge too much.

I'm about to try 32 all around, was running 28/32... I have more camber than you, with shims and lowering.
And I would stick with the tire size that the rim is at the wide end for. With
a stiff sidewall, any narrowness of a rim will pinch the beads in, and lever
up the contact patch on the inside and outside.
The next test-n-tune they have in my area, I will get a friend to take temps ASAP
on a skid pad, so I can make a careful judgement on pressures and alignment.
Probe-type temp gauges can be cheap enough, or borrow one...

Looks like ax use, over driving front end in tight corners and plowing.

Could be from the lower tire pressure. Try running them in hotter for a few session. However, you'll really need to focus on how the wear happens - it'll be harder to spot if you're not sure what to look for when monitoring.
