It doesn't sound like a bright idea to me. Shaving a pound off each rotor is a substantial amount. And plus you would have to shave the rotor so that it is still perfectly smooth, if the rotor is not smooth, braking will not be consistent and the car will shake a lot when you are stopping. I'm not sure if it would cool quicker. I'm going to guess that it would cool faster simply because there is less volume to cool. Carbon composite brake rotors would also probably cost you an arm and a leg. I'm not familiar with ITA rules so maybe someone else can help you out on that. Personally I don't think 4 pounds is that big of a deal. Especially for autocross. Just my .02.
