I have a feeling that the 14" stockers will do just fine for a lightly modded track 370Z. Obviously the stock pads and fluid may not be up to the task, but I don't see any reason why they shouldn't perform just as well as any other 14" kit. 4 large pistons can be just as effective as 6 smaller ones. Also remember that the 370Z is a bit lighter than the 350Z. I forsee a rotor/pad/fluid upgrade taking you pretty far on the sports package brakes. Also remember that only a few brake companies actually make big brake kits, the rest are private labeled. For example, the Ford Mustang "Saleen" big brakes are actually made by StopTech. Even Rotora brakes are private labeled. I don't know much about Akebono, but if they are big into private labeling like they do for Nissan, then they may already make some of the aftermarket brakes that you might think you are "upgrading" to
