Last night someone posted a question about drilling vent hole in the rotors. Mingster, I believe, posted about possible cracking if they were drilled and should be cast in. I stated the rotors were plate and not cast. THIS STATEMENT WAS IN ERROR. The rotors are indeed cast, checked them this morning. All of the other statements still apply whether plate or cast (i.e. I wouldn't drill em unless done properly). Sorry for any confusion.
