What you see in the pictures, is not Porsche. In fact, neither a Nissan 350Z, although it started its life as one. This is the creation of Shinichi Kameda, called Pana-Z, which debuted at SEMA in 2011.
The car is equipped with air suspension and rests on 22 inch VIP Modular rims. The huge brakes are hidden in the wheels, while the front and rear, is from a Porsche Panamera. In fact, it is not a Porsche Panamera, but a body kit intended for the Panamera, though many other parts are actually from the Porsche Panamera.
