You guys are getting all mixed up with sprung, unsprung, and rotating weight. It's not just that lighter wheels/tires remove unsprung weight (which they do), it's that they remove unsprung rotational weight. Rotational weight is the enemy of acceleration, braking, and handling (wheels have, like any other rotating object, a gyroscopic effect that resists movement along axes other than the current rotation).

People who spend the equivalent of the GNP of some small countries racing professionally have concluded that rotational mass at the wheel counts 4x more than non-rotational mass when accelerating and decelerating. I am in no position to discount their findings and will be far more likely to trust their conclusions than that of my fellow dudez on teh enterwebz. aight?

What about those of us that daily drive what is essentially a race car and want to improve ride, response, and control.
It amazes me that even in the Miata crowd so many don't realize the huge benefits of truly lightweight wheels.
Worst mistake I ever made in the ownership of my car was selling my OEM BBS (10lb) wheels. Who cares how much tire you can put on them? The car has never ridden, reacted or handled quite as nicely since.
