Its rotational mass which is more significant than basic weight reduction, which equates to roughly 10hp freeded up per 100lbs removed. It really depends on what type of driving experience you are after. CF DS also has a much higher elasticity than steal or aluminum reducing shock to the drivetrain. Anyhow, it's not a mod for everyone but worth it for some along with forged lightweight wheels, 2 piece rotors, etc...
