Not all 2 piece rotors are much lighter than steel single piece units. i work on alot of high end modern stuff which most cars have dual cast rotors with cast iron outer and a aluminum hub. When we weighed two piece rotors for direct replacements they were heavier by a good margin.
if weight is your ideal goal weigh the options literally
Most street guys who never see a track spend a good fortune for two piece rotors for cosmetic reasons as well. we see this often in the high end euro scene.
