They will be only to a certain point.
Plus, what is the weight of the larger setup?
If they weight more, then unsprung weight goes up, and that negatively affects a cars performance from acceleration, to handling, to braking, to MPG.

Larger rotors have a larger potential swept area if the pads are made to take advantage, which I have no reason to think they won't. But, I'd like to see the OEM brake spec on swept area vs the Msport brakes. And, it would interesting to see the swept area spec between US/N.America and the Euro market.
