Is there any resource out there that compares the OEM brakes of each car? And the break down of the changes between model years?

example, early years vs brembo's, then came revup models, then the akebomo's and so on

Generally, if I need to know if 05 Z brakes are compatible with a 07 G coupe, etc

 

Found some part numbers for comparison:

41001-CM40A -- 2005-2007 G35 Right Caliper (Also 2006 350Z share these part number)
D0206-ZA500 -- 2005-2007 G35 Right Rotor

41001-AM801 -- 2005 350Z Right Caliper (Same parts# as 2004 G35)
40206-AM800 -- 2005 350Z Right Rotor

These are cars with DE engines, I didn't look at HR engines.

 

I don't have a resource but I'm sure brembos from early year G/Z fit all non brembo G coupes to '07. They require no additional brackets.

05-07 Gs did not have a brembo option.

The non brembo Gs from 03-04 had single piston fronts/rear calibers. The 05-07 have a two piston front/single piston rear caliper.

The Akebonos came out with the new G37 coupe and are now offered in current G models (not sure about the G25).

The 05 z brakes should fit no problem

The revup models had no affect on G brake packages because they came with 05-up 6MTs which did not have a brembo option.

If anything I would compare the part numbers for the "spindle" or "hub" parts because that's where the calipers mount.
