Carbotech's website is not clear to say the least - not that nissan made it easy on them.

Are these the correct prefixes for their part numbers for '09-'11 g37?

320mm - CT888- (Front pads for AWD & RWD 4dr, non-sport)
330mm - CT1287- (front pads for 2dr, non-sport)
355mm - CT1346- (front pads for sport)
350mm - CT1347- (rear pads for sport)
307mm - CT905- (rear pads for all except sport)


also looks like stoptech is using same numbers?

 

that's about right...

 

Unfortunately the Carbotech description is a bit vague but at least you discovered that the prefixes coincide w/ Centric pads. The only one on the Carbotech that isn't real clear is the rear base brakes since they have different rotor sizes but use the same rear pads. The 330mm base AWD/RWD coupe brakes w/ 330mm rear rotors use the same pad #s as the base AWD/RWD sedan pads that are on the dinky 307mm rear rotors.
