zx14 is 300, busa is 320...so,even if you fit 'em, they will turn quicker at the same km, something that will result in higher temperatures...
wavy are nice to look at but worse in braking due to the fact that the braking area is less than the round ones...so...more heat again...
wave disks are mainly used in dirt where keeping the disk and pad clean is more important than keeping temperatures low...
if you punish the hell out of your brakes like i do,just put a radial master cylinder(ap racing or nissin), high pressure lines,carbon lorraine sbk 5 pads ,and you'll se the light...incredible stopping power...
