The RZ-DF is Advan's only forged wheel at the moment, and is actually forged by Rays (Volk). Yokohama has a couple other Forged wheels in their AVS line though.
The RS and RS-D are flow formed cast. However, just because they are cast does not mean they are not strong or light. Advan uses very high quality aluminum combined with quality castings and heat treatment, that gives overall strength and weight very similar to other Forged wheels.
Forging is just a technique...overall quality control goes a lot farther than just saying "cast" or 'forged"
