The current model Camaro has a differential cooler:

I know that long ago Winston Cup cars used diff coolers, too, but theirs simply cycled the diff oil itself through a cooler using a pump driven off the drive shaft with a little belt. The Camaro cooler uses an internal heat exchanger with transmission fluid cycling through it.

I suspect the only time you'd need such a cooler is if you're planning to spend an hour far above 100 mph. So, overkill for a street car? Or a good idea? It's a fairly simple project to add the Winston Cup type to pretty much any diff, screwing fittings into the fill and drain openings and plumbing them to a pump and cooler.

Thoughts?
