Specifically the difference between 03/04 350z oem rotor size and pads compared to the 03/04 g35 oem rotor and pads? Reason I ask is a friend needs rotors and pads for his 350Z and I have a barely used set from my 04 g35

 

During those years the only difference I have observed is pending on Brembo and Non - Brembo applications. I want to say 07-08 is the first change to the brakes and other suspension components that actually come with larger rotors, calipers and different spindles.

Correct me if I am wrong.

 

I have 04 350z pads and rotors on my 04 sedan.

 

06 is when Nissan upgraded the whole brake system on the 350Z. I believe the 06 350Z brakes are the same as the 05+ G35 brakes... They're 2 piston fronts with a larger brake pad.
