We have plenty of pads to choose from to include OEM maintenance advantage pads, that are cheaper than the standard OEM and also include the shims, which the standard OEM pad doesn't. The OEM part#'s you have listed are the correct pads for Sport package brakes. Who knows what brand name Nissan uses for their branded "OEM" pads, they come in a Nissan Box with no other markings. All we know is that AKEBONO makes the brake calipers, period.

That is the link to the brake components we offer for the G37. If it doesn't say (AKEBONO) in the title, then it doesn't fit the sport brakes. The description of each item also includes vehicle fitment.
In short we offer the following Pads, all listed on the website:
Hawk HPS
