The fact that the G87 6MT with cast wheels basically performs the same as the G8x 6MT with forged wheels.
I highly doubt you can feel any difference. This is urban legend and there is zero measured data to indicate it. I've swapped plenty of wheel setups for winters and never felt some kind of difference attributable to the wheel and not the tire. Yes, there is a theoretical benefit, but it is very small in reality. Many people pushing this just want to sell you $$$ wheels.
