They are forged. This is from their website:
With over 30 years of combined experience in the automotive wheel industry Forgestar Performance Wheels has bridged the gap between forged wheels and cast wheels. Forgestar Performance Wheels is proud to introduce the world's first one piece lightweight rotary forged custom flow formed wheel lineup.
Rotary Forged Flow Forming is a production procedure that turns the wheel (or rim section) over a special mandrel and three hydraulic rollers using tremendous pressure. The pressure and turning then force the rim area to form against the mandrel, creating the shape and width of the rim. During Flow Forming, the rim actually "flows" down to create the full rim width. The pressure applied to the cast rim actually changes its mechanical properties, so its strength and impact values become similar to those of a forged rim. That translates to up to 15% less weight when compared to a standard cast wheel. Our technological breakthroughs in heat treating allow us to increase dent resistance without having to make the wheel heavier.
