For that supercar-worthy price, you'll be getting a number of race-derived parts. As we covered in our preview post, that will include a strong roster of safety equipment, including a full roll cage and six-point harnesses that will keep you pinned in a purposeful racing bucket. The standard 18.5-gallon fuel tank can be replaced with an optional 26.5-gallon setup, while a central fire extinguisher keeps things from getting too hot out on the track.
Mechanically, the Clubsport adjusts the Cayman GT4 formula for the track. The road car's 3.8-liter flat-six engine is still mounted amidships, but it's paired with super-quick, six-speed dual-clutch transmission, the critically acclaimed PDK. It's the suspension, though, that sees the most dramatic changes, as Porsche has pressed the front and rear strut suspension from the 911 GT3 Cup into duty for the GT4 Clubsport. The new system is lighter, and contributes to the track star's 2,866-pound curb weight. That's nearly a 100-pound drop over the road car. A set of four 15-inch steel rotors clamped by six-piston calipers up front and four-piston units in the rear should deliver stopping power as impressive as the cornering and acceleration.
Amateur racers interested in the new coupe can purchase it directly from Porsche Motorsports North America for competition in the 2016 racing season. Homologation is still being hammered out, but Porsche expects the GT4 Clubsport to be certified for the "VLN Long Distance Championship Nürburgring, the Ultra 94 GT3 Cup Challenge Canada, the PCA Club Racing Cayman GT4 Clubsport Trophy East as well as for other club-level competition events around the world."

World premiere in Los Angeles
LOS ANGELES, Nov. 18, 2015 /PRNewswire/ -- Porsche has added a new sports car for amateur and club racing to its Motorsports fleet: The Cayman GT4 Clubsport celebrated its world premiere today at the Los Angeles Auto Show. The 385 hp (283 kW) mid-engine entry level racer for motorsport, which is not legal for road use, is based on the successful street-legal Cayman GT4 sports car. Sales of the racecar by Porsche Motorsport North America start with the unveiling at the auto show.
Just like its well-developed production sibling, the Cayman GT4 Clubsport is powered by a 3.8-liter flat-six engine, positioned directly behind the driver's seat. The racing version features a modified six-speed Porsche double clutch PDK transmission with shift paddles on the steering wheel and a mechanical rear-axle locking differential specifically for racing. The lightweight strut front axle is taken from its big 911 GT3 Cup brother, which is campaigned in 20 one-make Porsche championships around the world. An enhanced lightweight strut suspension with transverse arms adopted from the 911 GT3 Cup, is at the rear. The racing brake system features large 15-inch (380-millimeter) steel brake discs all round. One-piece, six-piston aluminum fixed calipers are located at the front, with a four-piston equivalent at the rear. The anti-lock brake system features twelve settings. The Electronic Stability Program has been recalibrated for slick racing tires. The power steering is operated electro-mechanically.
Tipping the scales at just 2,866 pounds (1,300 kilograms), the Cayman GT4 Clubsport, is a virtually turn-key racecar, delivered from the factory with a welded-in safety cage, a racing bucket seat as well as a six-point harness. The North American version comes with an 18.5 gallon (70-liter) or an optional 26.5 gallon (100-liter) FIA FT3 safety fuel tank. The car also comes with a central fire extinguisher system. Mounted on the front axle are 18-inch five-bolt forged wheels with 25/64-18 tires while the 18-inch five-lug forged wheels at the rear have 27/68-18 tires. Michelin® supplies the racing slicks.
In the USA, the new Cayman GT4 Clubsport racecar is available directly from Porsche Motorsport North America for $165,000.
For 2016, homologation is anticipated for race series such as the VLN Long Distance Championship Nürburgring, the Ultra 94 GT3 Cup Challenge Canada and PCA Club Racing Cayman GT4 Clubsport Trophy East, as well as for other club-level competition events around the world.
