Finally, to be clear on one last stupid question - once the cord becomes even slightly visible, its time to trash the tires, correct?

For safety, yes, you should toss them. If you had a dedicated drift car and could afford to pop a tire while drifting at a safe venue, you could flip the tire and run it slightly longer, but even then, it's not really worth it.

Cold psi... for street use only, I'd run like 35-36

My ZIISS would look just like that if I street drove them another 3k street miles or so I think, 22k DD miles, 4x track days, 1x season of autox (~50-100 runs) and they've worn similar to yours (no cords yet, but similar tread depth) and I'm going to MPSS as I've got RE-71R's for autox and I'm not trying to set any records at track days. My rear camber has floated around -1.5 to -2.6 degrees over the past ~2 years I've had the tires, my front camber is in the -3 to -3.6 degree range when driving hard (zero toe at max negative, toes out as I go positive) and I go full positive on the camber plates for street driving, iirc about -2 degrees, -0.3 degrees total toe out at that setting. Totally happy with them but they heat cycled out within the first year I'm fairly certain.

As above, seems like you're in a life vs. grip conundrum. And yes, trash when the cord shows, ideally you'd be done based on wear markers and tread depth based on manufacturer recommendation (they know when the good rubber runs out, some tires are good to the cords, some aren't), but we're all trying to save a few bucks.

Thanks again guys. Looks like I'll pick up another of the same exact set and live with the increased cost.

I originally figured that with enough negative camber, you would promote inner tire wear with an increase in pressure. Is my understanding backwards, based on the recommendation to increase psi rather than drop it? I was running around 30 psi on the street, occasionally a tad less in canyons...

Try the RC1 since you primarily street. They're far quieter, and have less warmup time. They don't tolerate overdriving as much though.
