UPDATE: I have indeed confirmed that the z32 rotors were thinker. 280mm X 30mm. However I still can't confirm the effect it would have using the 300mm X 26mm in place of the z32'z rotors.

Take a look at these pictures demonstrating the differences.
And here is an overview of all 3 types
Mind you once you clean up these calipers they look MUCH better. Hell powdercoated they look like a BBK
And here are some pics of how they looked on my '97 240SX I had. I did a gloss black with white lettering...
Theyre actually pretty big, you can see how big in relation to my mousepad its on and my mouse and keyboard etc..

The z32 30mm rotors are 280x30. The nonbrembo 03-05 rotors are 295.91 x 24.13. These IMO are not much larger and aren't thick enough to be worth using. The 06 nonbrembo rotors are 319.79x27.9. These are bigger and better but still not thcik enuff. Now.. all the brembo rotors from any year are 324.10 x 29.97. They are practically 30mm thick, exactly what the caliper were designed for. They're also 1/4 shy of being 13" rotors and are 1.74 inches larger! thats ALOT bigger than the original z32 rotor. All we need is for someone to design a bracket that bolts to the Z33 knuckle and spaces the caliper properly to use it with the brembo front rotors.

In this install the bracket held the caliper too high and the pad outer diameter was 3-4mm above the rotor outer diameter - getting the caliper down where it needs to be shrinks that gap considerably - going to a 12"+ rotor leads to interference here as the inner surface of the caliper is designed for a 12" or so max rotor.

We know this information already. Thanks for the re-cap.

Ok then.... Why are we sweating the 30mm calipers when we know that the 26mm will work better on the non-brembo rotors? I know everyone wants it to have the biggest rotor we can fit in the wheels but I never thought this would end up being a alternative to a real BBK. Just more of an upgrade from what some of us have now. $500 tops.

If it does work then I'd have to say that about the largest you can go without have to alter the caliper in some way or another.
Anyone else have any thoughts on the matter?
Although the real question hasn't really been answered yet.... Will the Z32's 30mm have the same clamping force on the 24mm non-brembo rotors as the 26mm Z32 calipers on the same rotor? Is it just a matter of nissan making the caliper just a bit wider in the inside yet kept the over-all caliper body the same?
