Heh, it's not so much the GM part as it is the Michelin and brembo parts.

The physics works in favor of water-to-oil coolers due to the way higher density of water compared to air.

Porsche is really impressive with their powertrain cooling. They also have ducts and scoops all over. They also have 3 radiators so effectively they overbuild the cooling and put the heat from the oil into the cooling system. Do the RS cars have dedicated coolers?

and edit: for DD, my air-to-oil OC keeps things around 180 in the summer, and dangerously low in the winter. i usually tie some cardboard over the rad to keep things warmer.

You don't want the engine oil that low. You want it above the boiling point of water or else water in the oil (condensation, etc) will accumulate and never boil off. You want your engine oil around 220. On my truck in Michigan, I added external dedicated trans and engine oil coolers, but I ran them before the in-radiator coolers. This way I got extra cooling but if I over cooled them when I wasn't towing in the winter, the coolant would heat them back up.
