Oops, Porsche Caymans Aren't Supposed To Have Three WheelsStef Schrader1/27/17 1:06pm41EditPromoteGo to permalinkHello, No. 4. Team TGM Porsche Cayman GT4. I don’t know if you can see it because it’s behind you, but I think you may have felt it. Last I checked, I don’t think you’re supposed to only have three wheels. You’re totally missing something, man. Like a wheel. An entire wheel.
