Btw, I am under the impression it was the VED that's featured in MI4 not the i8 but I might be wrong.

Decreased non suspended and rotational masses are also a benefit of that solution. There are packaging benefits too.

Thanks! That's good to know. I didn't realize that the contact surface would stay the same.
