With all the gundrilling and slightly slimmer counterweights, the Manley weighs in at around 1 pound less than a factory crank. One pound equals 453.5 grams, so 30 grams isn't much in terms of overall weight but it's huge when balancing. Factory EJ257s are typically within a few grams of zero in terms of balance but I would imagine QC is stricter at the forging level than cranks like the Manley or K1.
