According to the example above, the sedan's wheel centers are .205m / 8" below the COM, so that would put the extra weight of xDrive lower than the COM. If so, that should have the effect of lowering the vehicle's COM with xDrive.

I'm also having trouble following the effect of the 10mm lowered ride height for RWD with sport suspension. In terms of meters as the unit of measurement used in the example, that 10mm is only 0.01m.

Am I missing something?

Thanks
