The short track guys use 12.18 X 1.25 wilwood GN48 curved vane rotors and superlight calipers. A short race for these guys is 25 miles on a 1/2 mile oval track(pavement)and do 100 stops from about 125 down to about 60 in a row.The cars weight about 500 pounds more than our 40,s.

It's not the diameter of the rotor that makes for a good brake system its the amount of heat that can be rejected over a given period of time.

12 inch rotors are plenty big "IF" they can reject the heat. Quality curved vane race equipment like Wilwood, Alcon, etc should not have a problem with our normal weekend track day type usage.
