Alright, well im ready to do the Z calliper upgrade, but i cant decide whether or not to use the 13" cobra rotors, or stick with the 12.6" max rotors. I wana go with the 13"s but are there any issues with the brackets or rubbing on the control arm or something? I remember reading about something bad...

eh, well give me ur opinions...whoever has done this...

And where can i get all the parts i need for the upgrade?
