Ordered my G30 with 668m wheels.
Does anyone know if G30 668m 20" wheels are forged or cast iron?
At the same time I am looking for a second wheel set to be used for autocross (will be reusing PSS that came with 668m wheels for that)
20" is 669m is listed as Forged based on the link:

Also, are f90 M5 706m wheels forged?
Thank you
