This 2014 Porsche Cayman (981) originally came with a 2.7 L flat-six. It is now powered by a 3.8 L DFI flat-six from a Porsche 991 Carrera S with a GT4-spec exhaust. Behind that is the factory six-speed manual transaxle with a Guard limited-slip diffential and GT4-spec clutch. The sport car rides on Bilstein PSS9 coilovers and Road Sport Supply (RSS) GT3-style control arms. It stops thanks to 991 Carrera S-spec calipers and drilled and vented rotors. A set of Michelin Pilot Super Sport tires are mounted on Carrera S 20-inch wheels. The Cayman is for sale on Bring a Trailer located in Birmingham, Michigan.
