When Porsche debuted the Cayman GT4, they broke with a widely held belief that Porsche was not as interested in letting the mid-engined Boxster/Cayman lineup reach its full potential, as that would mean competing with the rear-engined 911, their defining model. The GT4 gave ample evidence to the contrary, and made 911 power and performance accessible at both a relatively lower price point and in a car that was a little more forgiving for novice drivers.
Now Porsche debuts a GT4 that is specifically for the race track. The Clubsport has basically the identical body as the street GT4, a testament to how well-planned that model's aerodynamics were.
Weighing in at 2866 lbs with its welded safety cage from the factory, the Clubsport features a lightweight strut axle in the front and a strut suspension with transverse arms sourced from the 911 GT3 Cup. The large 380 mm steel brakes on all 4 wheels feature six piston aluminum calipers in front and four piston aluminum calipers in the rear.
The 3.8 liter boxer-6 matches the output of the street GT4 with 385 hp.

Stuttgart. Porsche has added a new sports car for recreational and club racing to its fleet: The Cayman GT4 Clubsport celebrated its world premiere today at the Los Angeles Auto Show. The 283 kW (385 hp) mid-engine racer for motorsport newcomers, which is not road homologated, is based on the successful street-legal Cayman GT4 sports car. Sales of the racing car start with the unveiling at the trade show.
Just like its exceptionally race-worthy production sibling, the Cayman GT4 Clubsport is powered by a 3.8-litre flat-six engine, positioned directly behind the driver’s seat. The racing version exclusively features a modified six-speed Porsche double clutch 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 Porsche’s 20 one-make championships around the world. Working at the rear is an enhanced lightweight strut suspension with transverse arms adopted from the 911 GT3 Cup. The impressively dimensioned racing brake system features 380-millimetre steel brake discs all round. Fitted at the front are one-piece, six-piston aluminium fixed callipers, with a four-piston equivalent at the rear. The anti-lock brake system can be adjusted in twelve stages. The Electronic Stability Programme has been expanded for slicks. The power steering is operated electro-mechanically.
Tipping the scales at just 1,300 kilograms, the Cayman GT4 Clubsport, delivered ex-works with a welded-in safety cage, a racing bucket seat as well as a six-point harness, is truly lightweight. The basic version is equipped with a 90-litre standard tank, with an optional 70-litre or 100-litre FT3 safety tank available. Mounted at the front axle are 18-inch five-bolt forged rims with Michelin tyres (25/64-18), with 18-inch five-bolt forged rims at the rear with 27/68-18 tyre dimensions.
The new Cayman GT4 Clubsport, which is available from 111,000 euro plus country-specific VAT, can be ordered immediately from Porsche Motorsport in Weissach. For 2016, homologation is planned for race series such as the VLN Long Distance Championship Nürburgring, the SRO GT4 series, the Pirelli GT3 Cup Trophy USA, the Ultra 94 GT3 Cup Challenge Canada and for club races run by the Porsche Club of America, as well as for other club-level meetings around the world.
