Maybe the whole oil starvation issue is causing them to go safer and put in 5w-30.
oil starvation happens when the oil pickup cant suck in as much oil as it needs, the grade of oil would make no difference, either the pickup is clogged or under a high G maneuver the oil is pushed away and thats when issues arise, the viscosity of the oil wont help much if at all, plus a thinner oil would be safer theoretically (easier to flow past the clogged pickup).

On gen 1 cars it was pretty conclusively proven that 0w-20 with an oil cooler was the most ideal for a track car seeing hot temps, I run track days on 0w-20
