i emailed irotors about a setup for the Z. they have one after all for the non brembo cars(it is not on their site yet) I replied to get some more specifics on them; how are they made, sizes, some of the questions that were asked in this thread. I am just going by my experience with them and their rotors but once i get the info to you all, we will see. He quoted me an initial price of $269 for all 4 shipped. i think the zinc coating will be extra though.
