I spent a fair bit of time confirming this, it’s not on any of the 350Z forums for 2006 350z roadsters.

2006 Nissan 350Z Front Center Jack Point (Z33): If you’re trying to find the front center floor-jack location on a 2003–2009 Nissan 350Z, the factory garage jack point is on the front suspension crossmember. On my 2006 350Z it looks like a small raised “belly button” or dimple underneath the center of the car, between the larger round subframe mounting points. These photos show the actual 350Z front center jack point.
