Can someone tell me exactly what comes up for this part number: D815 (I think)

I'm just trying to see if I have the wrong brake pads and I can't figure out where to look it up. I checked infiniti site and i looked on numerous parts sites but couldn't find it.

Thanks

 

so I found this, and it's the pads I have, and it looks like it'll fit on my 2005 G35 w/o brembo's but Kris said they looked too small or something? anyone ever run these?

so i called hawkperformance and he said i need 387F .547 instead of the 268F .665 that I have, so I need to call back the brake people but they must be busy :-/ not answering anymore

 

so this 387F .547 is an M45 brake pad! :-/ I'm so confused as well as the salesman I was speaking with. Why would the catalog not even mention a G35 using a pad similar to the 387F? It says 03-05 use the 268F, but the pad is more than 1in shorter than the pads I have on right now. Can anyone confirm that the M45 brake pad is the correct one to be using in the front of an 05 nonbrembo coupe?
