Current Topic:
aluminum vs. steel in brake disc
i am involved with a racing program in which we currently use a hard-coat annodizing on aluminum rotors.  this annodizing greatly reduces wear and allows us to use these rotors for 3-4 races before changing.  we run a soft compound pad which must be changed after each race.  previously we've used a ceramic coating which performed even better in terms of wear and braking force, but this coating is expensive and for our application the added cost outweighed the benefits.
