Is there really that much difference? The cast iron ones are pretty heavy, and the 4 pot aluminums off the w220 (relabeled brembos?) can be had relatively cheap.

Page 5, "weight", should give some insight. It lists the 500e brembo 4pot caliper.

This difference is quite large. The aluminum brembo 300mm fronts are super light compared to the 334s
