Not only cosmetical upgrade.

Since the calipers is the same, the force between the disc and brake pads is also the same.

But the bigger rotors generates more torque on the front wheels (friction force times leverage), i.e. more stopping power.

The 374mm rotors are 7.5% bigger than 348, the stopping power (on the front axle) will be increased by the same amount.
