I have M3 wishbones and Dinan camber plates.

At my last event, I was running about 38 lbs pressure hot. I start around 34-35 lbs cold in my hotel parking lot, and then check with a pyrometer after my 1st run. The pyrometer almost always reads close to perfect after the first run. Then I usually have to bleed about a pound after 2nd and 3rd runs, sometimes on one side, sometimes on both sides.

That sounds similar to my experiences, although I run slightly higher hot pressures than you. I find I have to bleed out pressures until the middle of the afternoon, to keep the hot pressures no higher than 40 psi.

BTW, how does your car handle on the street with -1.8 deg camber? Is the steering overly sensitive or twitchy at all?

I don't think it's twitchy or overly sensitive at all. I do think it feels like it grips harder as I start to turn into a corner - not sure if I'm imagining that, but it feels like a plus not a minus. So far I don't think there's any downside.

My installer and several people here said -1.5 was the limit for street before it would cause uneven wear. But I think I'm wearing my tires as much or more on track as I do on street, so by that logic, something like -2.3 should give me even wear.
