Oh yeah, those are 22-24 lbs. each. Not too shabby for a cast wheel.
Interesting sales speak for the forgestar "flow form cast" wheel:
"Flow Form Casting 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. During Flow Forming, 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."
