You are forgetting about leverage. The farther from the center the less force it takes to slow it.Originally posted by BOMEX DSM
IF you own the kit u will noticed that the 13inch kit doesnt use the whole rotor it doesnt put to use the inner part of the rotor where the hat belongs. As u can see on the picture on my profile u can see the darker area where the caliper clamps and the lighter inner area where it doesnt. The 12inch uses the whole rotor meanwhile making it the same clamping surface of the caliper so the 13 isnt better than the 12 just looks better and prevents u from using 16inch wheels and some 17s. Believe me i have first hand experience with the brakes as i tried to fit some stealth RT/TT wheels and they wouldnt clear the 97-99 GSX wheels however clear both being 17inches. Hope that helps and if u have any other questions feel free to PM me.
