Also for ease of reference, I measured up the rotors and pads while I was there.
Fronts are 320mm diameter, 28mm thick, 50mm high which makes them DB2308. DBA don't list them for the hybrid but they are listed for the VQ25 and VQ37 models
Rears are 308mm diameter, 17mm thick, 64mm high which makes them DB2313E. Again DBA don't list them for Fuga but the listing is there for Infiniti Q70 rear.
Front pads are DB1696, bendix don't list them as Fuga but they do list them for M35h Infiniti
Rear pads are DB1509, again bendix list them for M35h Infiniti not Fuga.
