a quick (i assume even though im no dev) and logical fix, bulkheads fitted to ship determine damage needed to be done to target before you can damage internal subsystems such as power plant, frameshift drive and power distributor.
so lightweight alloys being free you would only need to reduce target base hull hp to 90%, reinforced alloys 70%, military, mirrored and reactive composite 50%. since hull reinforcement packs add hull hp they now become useful because it adds extra buffer before your juicy bits can damaged
