4 events in (all on asphalt -- Bristol, Philly, Bristol 2.0, local BMW club), I've learned that this car is *difficult* to drive at the limit. It's really loose, and right now probably just too stiff for 285s, particularly in the rear. Even on a tight local course, my codriver (a DSP contender) and I were running fairly mid-range MCS settings on the front dampers and basically bottoming out the rear.
I'm at 1000lb/800lb with factory Nismo bars, and disconnecting the rear at the midday break of our local event certainly helped -- not enough to balance the rear damper settings back upwards though. First I'll be going for some bar changes. I find it ridiculous that the front and rear bars on this car are both 27mm. I would have tossed it out ages ago knowing that. Potentially softer springs if that's not enough of a fix, and if we don't move to 315s next year.
We also found ourselves instantly getting ABS while braking out of a faster sweeper. At first I assumed I'd finally encountered the issue everyone has been complaining about despite having a factory diff cover and HPS pads, but it sounds like the opposite of that problem given the previous discussion.
When I got home, I found some oil spewing out of a loose sandwich plate fitting and probably on to the front right corner, likely getting to the tire and/or brake disc, which coincidentally would have been under the most load at the time. For now I'll attribute the ABS to that unless you guys have other thoughts...

Reason: more than a little oil, to be fair...
