So far, all the pics that I've seen that show the rotors, showed cross drilled rotors. (IMG:http://www.frrax.com/rrforum/style_emoticons/default/mad.gif)

Correct me if I'm wrong, but the C5 Z06 still used solid rotors?

Porsche and Ferrari use rotors that have the holes cast into them when they are made, not cross drilled later. I can't speak to the new C6Z51/Z06 rotors on that. I do know, that even Porsche for a while used blank rotors on it's top line performance cars. My 88 944 Turbo S has blank rotors, while the base 944 Turbos came with "cross drilled" (cast) rotors. The reason? Porsche knew way back then that rotors with holes in them are really just for appearance. The only reason most Porsches and Ferraris today come with rotors with "cross drilled" holes is because the customer expects it, not because of any performance gains. Unfortunately it looks like GM is taking the same route. Personally, if they are going to use "cross drilled" rotors, I would prefer to see them on the base C6 and use "blank" rotors on the performance models (Z51/Z06).
