Yes, we are saying the same thing.
My F80 experience has taught me that this is a huge upgrade, even just in normal driving. Nothing ever jostles the rear end - the car always tracks precisely where you put it regardless of what the tires may encounter. It's remarkable and gives immense confidence. The F80 also rides significantly 'harder' than the E9XM so no free lunch. Rear impacts are sharp and pointy and ultra direct - good for performance bad for comfort. Surely the solid mounted subframe contributes to this.
It's just that the stock E9XM is very good in this regard and doesn't 'need' an upgrade in this area even though improvements are possible.
