The stock oil cooler definitely does not cut it. I would strongly recommend you plan to have cool-down laps unless you are stuck behind traffic. For a 20 minute session I think I got usually like 5-6 full laps in, not counting first warm up and ending half a lap after checker. So I did warm up, 3 laps, cool down, 1-2 laps, checker i think. Probably better if you plan warm up, 2 laps, cool down, 2-3 laps, checker. I would also recommend you treat your warm up lap like a warm up and not to go crazy and overheat your engine on a useless lap.
According to motoiq, 280F is bad

See, I can imagine a 90 degree day raising old temps, usually right now, especially in Jan when i begin my "tracking season", ambient temps never exceed 65-70 so i bet that will help a small bit. If I find that im getting to the 260-270 mark rather easy i will def do a cool down lap. Maybe its just me, but i think the guys (like you and maybe some others) are way more intense on the track than I am. I usually run 2:12's at autoclub and consider myself a casual track day guy. some of these guys are brutal which im sure makes the oil temps scream! Plus maybe 7AT dont get the engine as hot because the RPMS might not get as wild as a 6MT? just a theory....
