of the hatted rotors is Zinc plated. At circa $2,000 for a front set I never expected them not to be. I have been in hate with the rusty look, clearly visible through my open SSR GT-1 wheels, since the day I got them.
Z1 makes adapters for the calipers of the 370Z (Akebono). The rotors are all iron though and likley a heavier arrangement than StopTech or Brembo.
