Show me just ONE OEM cast wheel that weighs anything close to 10 pounds. (20 pounds is closer to realty for most 15" and 16" OEM aluminum wheels).

You can't - despite the fact that such a wheel would be "win win" for the manufactures since they're be CHEAPER to build (less material) and would increase a slight gain in fuel economy (lower weight and rotating intertia).

So why don't they do it?

Answer: Because such a wheel would produce a flood of warranty claims in the form of bent rims.

since when are we talking OEM's?

OEM wheels also need to stand up to some dumb girl running over a curb at 35 mph and being able to go home and not tell mommy.

I'll try and re-organize our questions for you in a easier to read format. BRB.
