Lower unsprung weight, what is the advantage?

Okay, so you hear the expression '...to lower the unsprung weight' particularly with alloy wheels over steel ones. But apart from a slight weight advantage, what does lowering the unsprung weight really do? I know lighter equals faster, but surely this applies to sprung weight as well as unsprung?

I was thinking more of track cars, particularly the beautiful big Healy that I had the pleasure of fitting a clutch and gearbox into at Spa last weekend.
