The OP’s 2 piece aluminum hat and steel rotor ring combination is going to be closer in weight to stock steel rotors than to the factory option carbon rotors so even less of a performance benefit.

2 piece rotors have a lot of advantages. HOWEVER, the stock BMW ones are two piece as well (look closely. Just because YOU can't take them apart doesn't mean they aren't two piece). The carbons are just two damn expensive. If they cost what the steels cost, I'd use the carbons all the time. But $4000? per? vs. $400. No way. I just couldn't see that much of a difference. My GT-R I could see a little bit more.
HOWEVER, if this two piece rotor was from Brembo, or stoptech, or girodisc? In a heartbeat. I'd at least TRY it. Maybe end up going back to the BMW's.
