I understand the different set ups. But are they backward compatible with each other? I have a 2003 G35 Sedan.

In other words, can an 03-04 Coupe Non-Brembo rotor, 05-06 Sedan rotor, or 05-07 Coupe rotor fit on my 2003 G35 Sedan?

The differences between the 03-04 Sedan rotor vs the 03-04 Sedan Coupe rotors seem minimal. And the 05+ rotors are a bit more significant.

Thanks for the help!

 

With the sedan you can't run 05-06 rotors up front from the coupe or the sedan as the calipers/rotors are smaller on your car. Infiniti made major improvements on the brakes starting with the 05 2wd versions, and carried that over to the X in 2006. Not sure about 03-04 coupe non-brembo though.

 

I have an 04 sedan and I bought Marcus's used 05 calipers and rotors. It was a direct swap and they work amazingly better than my stock ones. Best bet is to do the same if you want larger rotors

 

That's what I assumed for the 05+ rotors.

But, will 03-04 Coupe rotors still be compatible in my 03 Sedan? The differences are subtle as shown below... but I want to be 100% sure they are backward compatible with the 03-04 Sedan.

03-04 Sedan
Front: 11.7-inch X 0.9-inch power-assisted vented disc
Rear: 11.5-inch X 0.6-inch power-assisted vented disc

03-04 Coupe (Non-Brembo).
Front: 11.65-inch x 0.94-inch power-assisted vented disc
Rear: 11.5-inch x 0.63-inch power-assisted vented disc
I'm sticking with my OEM calipers. So my question still stands about other rotors working on the 1/1 piston configuration of the 03 sedan.

 

Anyone?

 

I'd think that they are interchangeable since they are so close in dimensions.
