The Porsche Cayman GT4 seems like an enthusiast’s dream. The stiff chassis and mid-engine architecture of the Cayman with the added power and performance that will finally let it eclipse the 911 like we all know it can. But a dream is all it has really been, at least officially. We have seen spy shots of a Cayman with crazy body work and huge wheels, but there has been no official word form Porsche that this car is even being considered. Or at least that was the case until someone at Porsche accidentally made a mistake on its Driving Experiences web page.
