Will Factory Brembo brakes, 350Z (Track, 35th Anniversary, Grand Touring, NISMO) fit a Nissan 350Z (Z33, 2003-2009)?

Q: Will Factory Brembo brakes, 350Z (Track, 35th Anniversary, Grand Touring, NISMO) fit a Nissan 350Z (Z33, 2003-2009)?

Unclear. Rear rotor size unclear. The front is consistent: 324 x 30 mm rotor, 4-piston caliper; the rear is 22 mm thick with a 2-piston caliper. The rear diameter conflicts: 332 mm (13.07 in) per the 2003 manual and a 2003 G35 coupe spec table; 322 mm (12.68 in) per the 2007 manual, the 2008 press kit (12.7 in) and Autoweek's 2003 Track report. A forum post quoting a 2004 G35 manual gives "322 x 22" next to 13.07 in, which does not add up. We show both and do not pick one; no source says the size changed by year. Measure the rotor or match it to the calipers you have. Tier 2.
