The problem is the ABS controller. They added a two new features to the 370Z which don't really work properly, Dynamic Brake Proportioning and Brake Assistance.

The biggest problem is the Brake Assistance, this feature actively boost the brake pressure you apply when you hit the pedal suddenly but not hard enough to engage ABS. It boosts the pressure such that you immediately go into ABS. Auto-X drivers are always hitting the brakes suddenly because we always leave braking to the last possible second. The problem lessens if you get onto the brakes progressively but if you go into ABS manually you still have the issue.

The second problem is related to the Dynamic Brake Proportioning and the ABS programming, and to a certain extent, heat. It is very easy to overheat the front brakes on this car at Auto-X especially if co-driving, there is simply no airflow at all. The ABS controller loses it's mind when the front brakes start to lose effectiveness compared to the rear brakes, this is a severe programming problem. The solution I have found is to run a low bite, high temperature front pad, and a lesser rear pad. This combats the bias issue and the temperature issue.
