Yet, on the other hand, shouldn't that unsprung weight add to the grip (reducing sprung shift effect)? Bumps can be handled by suspension and tires while inertia is a subject for engine/brakes power.
What I felt driving a new courtesy 3 Series with basic brakes was surprising uncertainty whether it would stop or not. I guess it's floating calliper against fixed support effect.
