My car was at about 6k miles when I took this sample after the last track event of the season (it's a DD, but super short commute). 1875 miles over about 6 mos, roughly 3 hrs total of track use (kart track lapping, 4 hot laps per session, .9mi track). Oil used was 5w30 300V. I'm concerned about high aluminum (12) and iron (11) on this first UOA I had done by blackstone.

Would I be better off switching to 5w-40, replacing oil/filter every 3 mos/3 track days, or both? Or maybe my car has such low miles it's not broken in yet and this is normal?

I'll plan to look for some advice on that oil forum as well.
