Porsche Motorsport unveils Cayman GT4 Clubsport racing car for 2015 LA Auto Show

Article by Christian Andrei, on October 5, 2015

Porsche has unveiled its latest racing-only sports car at the 2015 Los Angeles Auto Show – the Porsche Cayman GT4 Clubsport. This not-for-the-road mid-engine sports car is derived from the street-legal Cayman GT4 sports car, both sharing the same engine – a 3.8-liter flat-six powerplant that develops 385 hp (283 kW). This engine is placed directly behind the driver's seat.

The racer weighs just 2,866 pounds (1,300 kilograms). The Cayman GT4 Clubsport, however, comes with a modified six-speed Porsche double clutch PDK transmission with shift paddles on the steering wheel. It also features a mechanical rear-axle locking differential that is developed exclusively for racing purposes.

It inherits its lightweight strut front axle from the 911 GT3 Cup racer and its improved lightweight rear strut suspension with transverse arms from the 911 GT3 Cup. Its brake system is developed for racing as well, with large 15-inch (380-mm) steel brake discs. Six-piston and four-piston aluminum calipers are fitted on the front and rear wheels, respectively.

Moreover, the racer's anti-lock brake system comes with twelve settings while its Electronic Stability Program has been recalibrated for slick racing tires. Power steering, meanwhile, is operated electro-mechanically. As a nearly turnkey product, the Cayman GT4 Clubsport comes with a welded-in safety cage, a racing bucket seat and a six-point harness, as well as a central fire extinguisher system.

Its 18-inch five-bolt forged wheels are wrapped with Michelin's racing tires -- 25/64-18 tires at the front and 27/68-18 tires at the rear. Its North American variant, meanwhile, comes with an 18.5 gallon (70-liter) or an optional 26.5 gallon (100-liter) FIA FT3 safety fuel tank.

For customers in the United States interested in the new Cayman GT4 Clubsport racecar, they could order it directly from Porsche Motorsport North America at $165,000. Homologation of the new Cayman GT4 Clubsport is expected to 2016 racing events like the VLN Long Distance Championship Nürburgring, the Ultra 94 GT3 Cup Challenge Canada and PCA Club Racing Cayman GT4 Clubsport Trophy East.

Exterior Design

Porsche Motorsport has created a racing version of the Cayman GT4 just for the track. This mid-engine Cayman GT4 Clubsport is powered by a 3.8-liter flat-six engine that develops 385 hp (283 kW).

It comes fitted with a Porsche double clutch transmission with shift paddles on the steering wheel as well as a mechanical rear-axle locking differential.

This racer also comes with a racing brake system with steel brake discs measuring 380 mm in diameter. Cayman GT4 Clubsport features a lightweight suspension strut front axle system derived from the 911 GT3 Cup.

Safety features on the Cayman GT4 Clubsport include a welded-in safety cage, a six-point harness and a racing bucket seat. Overall, this racing heavyweight is literally a lightweight at just 2866 lbs. (1,300 kg).

Porsche Motorsport is planning to homologate the Cayman GT4 Clubsport in 2016 to make it legible to participate in racing competitions like the Continental Tire Sports Car Challenge, the Pirelli GT3 Cup Trophy USA, the Pirelli World Challenge, the Porsche Club of America and the Ultra 94 GT3 Cup Challenge Canada.

Interested customers can order their new Cayman GT4 Clubsport at Porsche Motorsport in Weissach, or at Porsche Motorsport North America (North America).

Since the Cayman GT4 Clubsport is not road-legal, Porsche’s authorized dealers in the United States are not allowed to sell it. Porsche Motorsport will unveil the Cayman GT4 Clubsport – along with details and related images -- on November 18, 2015 at the Los Angeles Auto Show.

Press Release

New Porsche Cayman GT4 Clubsport for the racetrack

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 har-ness, 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 coun-try-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.

Using the recently released lightweight Cayman GT4 as the basis, Porsche Motorsport has developed a racing version solely for the track. The 385 hp (283 kW) mid-engine racer Cayman GT4 Clubsport will celebrate its world premiere on November 18 at the Los Angeles Auto Show.

Like its production sibling, the Cayman GT4 Clubsport is powered by a 3.8-liter flat-six engine. The racing version features a Porsche double clutch transmission with shift paddles on the steering wheel and a mechanical rear-axle locking differential. The lightweight suspension strut front axle system is taken from its big 911 GT3 Cup brother, which is campaigned in Porsche’s 20 one-make championships around the world. The impressive racing brake system is fitted with steel brake discs all round measuring 380-millimeters in diameter. Tipping the scales at just 2866 lbs.
