The track guide lists 15W-40 as the recommended oil for the ZL1 1LE for tracking presumably due to the higher lateral loads on that car.

I think you meant 15W50, and IIRC it was due to the amount of "throttle on Time" due to down force being higher so they require a thicker oil for the track.
All V8s can use 15W50 for the track, but the manual says to swap it out when you are done with the track. Where as for non ZL1 1LEs (ZLE's) we can use 0W40/5W40 Dexos 2 oil for the track.
