The theory behind fold-down seats making a car heavier is that the lack of a bulkhead in that area means that additional weight has to be added to the seats to pass crash standards and the chassis to maintain stiffness. Could be lighter on the M3, I have no idea, but that's why they have caused a weight penalty in the past.
