I have worried about this issue in the past and tried different things and where I am currently:

LN 2 QT Deep sump with X-51 style baffle for oil starvation issues
UD crank pulley for power steering pump longevity
Low temp thermostat
Double row LN ceramic IMS retrofit
10W50 oil
Oil temp and oil pressure gauges to monitor things
Switch that runs both rad fans on high
I am back to running my oil level 1 bar down from full on the digital gauge (I used to run down around 1/2 to 1/3 from the bottom bar). I haven't been having any AOS trouble but that may be track dependent.

I feel pretty good with this setup, running on 100 TW r-comps like Nitto NT-01 or Maxxis RC-1 and 200TW tires like Hankook R-S3.

I don't have any data logging but I do have a camera setup that captures the oil gauges so it is like a "poor-man's" data logging.

The 10W50 (I am running Miller$ nano 10W50) - the 50 part helps and yields better results and less dips than the 5W40 especially when hot - Mobil 1 5W50 is an alternative an on the Porsche approved list or Amsoil 15W50. I like the Millers because I can get 5000+ miles on each fill (mostly HPDE and to/from the track driving) and still get a good UOA with plenty of TBN left. The longer life helps mitigate the cost for me.

I still get dips in places, but they are not severe and my UOA are good and not showing any abnormal wear, so I am feeling pretty good.

Ultimately I would like to go dry sump, but it is $$$.

Cheaper than a 996TT though or an air cooled dry sump 911. And I really like the Boxster platform.

Future potential reliability mods - replace the OEM rad fans with SPAL fans to see if I can keep things a little cooler, maybe combined with new radiators.

A counterpoint - the guy I bought my tire trailer from traded in his 986 Boxster after 80,000+ street miles and many years of track days, with his only mod being lowering springs and r-comp tires (and he was fast, 4+ seconds faster than me at Roebling) had no trouble whatsoever and his car was still in great condition when he traded it in on a new Cayman...
