This 2016 Porsche Cayman GT4<\/a> (981) came from the factory with a 3.8 L flat-six. It is now powered by a 911 GTS flat-six built by BGB Motorsports with displacement increased to 4.2 liters. The motor features a stroker crankshaft, BGB Motorsports rods, 105 mm pistons, Nikasil cylinder coating, ported heads, BGB Motorsports intake system, and SOUL Performance exhaust headers. It produces 455 hp (334 kW) and 338 lb-ft (458 Nm) of torque. Behind the motor is a six-speed transaxle with a custom gearset and Guard limited-slip differential. The Cayman’s suspension uses JRZ RS Pro reservoir shocks and lowering springs. Braking is handled by Brembo six-piston calipers in front and four-piston calipers in rear. Both have slotted and ventilated rotors. Over those are BBS E88 18-inch wheels wearing Yokahama Advan slicks. You can view more photos and specs on the Bring a Trailer listing<\/a>. <\/p>\n
