CoronaSun can't rotate downwards...

I can also think of a workaround - bake your sun (or sun+sky) as a HDRI enviro. Just set up a spherical camera, and render it to a 360 .hdr image. Then load this as your scene enviro - and you can rotate it however you wish.
Another idea is to use the 3ds Max direct light instead of a Corona Sun.

Can’t bake it all out, as I need light selects for the sun and env lights individually. Hmm, it saddens me to think that my only option for now might be to use a direct light.

The problem with this workaround is that we can’t rotate an environment map properly in vertical direction. Would make a neat feature in CoronaBitmap I think I’ve requested this a few times.

Actually, we can rotate the environment map in all three axis. I worked it out while documenting some of my discoveries in this thread:
https://forum.corona-renderer.com/ How to wire seperate values to the U and V offset in CoronaBitmap?
basically, I wire the Y and Z axis of a helper object to the U and V offset values in the CoronaBitmap, then I wire the X axis of the helper to the ‘Degrees’ value in the CoronaBitmap.

Hi, currently, it is not possible to rotate the sun below the horizon as the simulation model doesn’t support it. We might actually change that in the future so that the colour of the sun below the horizon would be the same as on the horizon, but no promises there.

That would be perfect please.
