Axle weight?

The distance from the center of rotation is a factor in calculating the resistance the engine has to overcome, more than the total mass. Basic physics. A 12" 25lb. flywheel has less inertial resistance to overcome than a 14" 25 lb. flywheel as long as the mass is evenly distributed. Same with axles.

Unsprung weight reduction is the advantage of lightened axles, along with being able to distribute that weight more efficiently in the car.
