Wilwood brake sizes

[Panteracer]

Looking at upsizing things with my brakes
Looks like my 6 piston Wilwoods with 12.88 rotors has
the same Caliper as the 14".. hub is the same
also.. just change to 14" and tweak the mount maybe

How much do I really gain??? 14" vs 12.88.. cooling surface
for the rotor.. the Caliper is the same, pad size the same
Maybe for track conditions... I guess grabbing farther out
diameter takes less effort

any thoughts
