BIG front disks (13"+)

Unless your running a large front racing compound tire like a viper 295/18/30 there is no advantage other than heat disapation which you would only notice on a track vs the street.
I was hoping to learn something here because I could be wrong?
Nobody will debate me with thier hypothesis so maybe you guy's dont know either? (braking advantage in going from a 12 inch rotor to a 13 inch rotor)
I get going to the 13 inch rotors for the COOL FACTOR!!!! Looks COOL
